Castilla: the industrial pulse that never went out
When the sun hides behind the guardian hills of Medellín and the noise of the engines on the 65 goes silent, in Castilla another kind of music begins. It's not the music of the clubs in El Poblado or the bars in Laureles. It's a rawer sound, coming out of warehouses that once wove jeans and now house broken synthesizers, recycled drum machines, and voices that rap in a cadence only understood if you grew up among factories. This neighborhood, in the northwest of the city, was for decades the textile heart of Medellín. The chimneys of Coltejer and Fabricato marked the landscape, and the smell of dye and cotton was the official aroma. Today, many of those industrial warehouses are abandoned, but not empty. Since April 2026, collectives of experimental musicians, DJs who build sets with washing machine motors, and female rappers who write about the workers' struggle are taking over those spaces. This is not ruin tourism. It's a scene that moves in the shadows, with its own codes, and is worth knowing if you're interested in cultural resistance made into sound.
What to do: hunting sounds in the industrial twilight
In Castilla there are no event billboards or tickets on TuBoleta. The charm is in finding the event before it happens. Most parties and performances occur in self-managed spaces, occupied by collectives that negotiate with the warehouse owners or simply enter through a side door someone left open. If you arrive with the right attitude, you can hear everything from techno made with sewing machine parts to free jazz improvisations over samples of factory sirens.

Colectivo Ruido de Taller
This group has been putting together sessions in an old textile factory on Calle 89 with Carrera 56 since 2021. They use recycled industrial machines: they turn three-phase motors into oscillators, and knitting needles into guitar pickups. Their events are usually on Saturdays every two weeks, but the exact date is posted on Instagram with 24 hours' notice, in a story that disappears. Entry costs between 10,000 and 15,000 COP, and sometimes they ask you to bring a metal object to use as percussion. Don't expect a nice stage: the floor is concrete, the lights are construction spotlights, and the sound comes from speakers borrowed from a neighboring church.
Frente Rapero Castilla
If techno isn't your thing, rap here has a different texture. The Frente Rapero Castilla is a collective of women and dissidents who meet at Parque de la Iguaná (Carrera 55 with Calle 98) on Sundays at sunset. It's not a fixed stage: they sit on the floor, form a circle, and drop rhymes about gentrification, factory closures, and life in working-class neighborhoods. The lyrics are in Spanish with Paisa slang, but if you don't speak the dialect, they lend you a notebook with the lyrics written down. There's no alcohol for sale, but Doña Bertha, a local woman, sells lulo juice and empanadas for 2,000 COP each. The atmosphere is more like a literary workshop than a party, but the energy is genuine.
Noche de Motores (monthly event)
Once a month, an anonymous collective called "Motores" (with no known social media) organizes a session in an abandoned warehouse on Carrera 52 with Calle 95. The address changes each time, and you find it by scanning a QR code spray-painted on a specific lamppost (usually those on Avenida 65, near the Caribe Metro station). The code takes you to a Google Maps link that updates on the same day. Three DJs or experimental bands play there, ranging from drone metal to musique concrète. Entry is free, but they ask you to bring a flashlight (the warehouse has no lights) and some food to share. Arrive before 8 p.m., because by 10 p.m. the police usually do rounds and the event disbands in 10 minutes.
Where to eat or drink: stops before the noise
Before you go into a dark warehouse to listen to distorted synthesizers, you need fuel. In Castilla there are no designer bars or craft cocktail lounges. What there are are street stalls and neighborhood restaurants that have been feeding factory workers for decades. Here are three options that locals use as meeting points before events.
La Esquina del Chicharrón (Calle 89 #55-12)
A stall open from 6 p.m. to 2 a.m. Run by don Óscar, a 68-year-old man who worked 30 years at Coltejer. His specialty is chicharrón with arepa and hogao, at 8,000 COP per portion. He also sells Colombiana soda or panela water. It's the reference point for asking about events: don Óscar knows which warehouse is active that night, and if he likes you, he'll draw you a map on a napkin. That said, don't ask him for the Motores QR code: he prefers word of mouth.
Panadería El Obrero (Carrera 54 #90-34)
Open since 5 a.m., but on weekends they close at midnight. They sell yuca bread, buñuelos, and drip coffee for 1,500 COP. It's the place where the Frente Rapero musicians grab something hot before heading to Parque de la Iguaná. They don't have wifi, but the owner, don Luis, plays 80s music on an old radio. If you arrive after 10 p.m., they offer you the day's leftovers at half price.
Puesto de Arepas La 95 (Calle 95 con Carrera 53)
A cart that appears after 7 p.m., run by doña Carmen. She sells arepas filled with cheese, corn, or shredded beef, from 4,000 COP. It's the meeting point for Noche de Motores attendees, because it's two blocks from most of the warehouses they use. Doña Carmen knows when there's an event because the musicians tell her; sometimes she even lends them an old speaker she has at home.
How to get there and transport: moving in the shadows
Castilla is connected by the Medellín Metro, but most events occur in areas that are a 10-15 minute walk from the station. The nearest station is Caribe (Line A), although you can also get off at Tricentenario if the event is further north. From there, you walk west, passing Avenida 65, which is the main axis. If you're coming from El Poblado or Laureles, the Metro ride takes between 25 and 40 minutes, depending on traffic.
City buses also work: the Castilla-La América route (which runs along the 65) drops you off on Calle 89. But be careful: after 10 p.m., buses run less frequently, and on the neighborhood's inner streets there is almost no street lighting. It's better to leave in a group or take a taxi (yellow ones are still common here) from the Caribe station. A trip from El Poblado to Castilla by taxi costs around 25,000 to 30,000 COP in April 2026. Don't use ride-hailing apps if you're going to a Motores event: drivers sometimes refuse to enter unpaved or poorly lit streets.
A key fact: events usually end between 11 p.m. and 1 a.m. If you stay late, the only way out is to walk to Avenida 65 and catch a passing taxi. Don't expect to find public transportation after midnight on the side streets.
Local tips: the unwritten rules of the scene
If you're going to get into this scene, leave behind the expectations of a traditional concert. There are no bouncers, no guest lists, and no dress code here, but there are codes you must respect if you want to be invited back.
- Clothing: Wear dark, comfortable clothes, preferably second-hand. No flashy brands or designer clothing. Locals wear ripped jeans, underground band t-shirts, or work overalls. Boots or closed-toe shoes are mandatory: the warehouse floor has broken glass, nails, and oil. Don't wear heels or sandals.
- Interaction with artists: Don't ask them for photos or interrupt them while they're playing. Here, the music is respected in silence. If you want to talk to a musician, wait until their set is over and approach them with a specific compliment (e.g., "that bassline reminded me of the textile factory motors"). Asking "where did you get that sample?" is a good icebreaker.
- Don't record without permission: Many events have a "no cell phones" policy. If you see no one is recording, don't do it either. Some collectives allow photos at the end, but ask first. The idea is that the experience is ephemeral, not content for Instagram.
- Bring cash: No one accepts cards or Nequi at these places. Entry fees, food, and beers (if available, sometimes they sell Poker for 3,000 COP) are paid with 2,000, 5,000, and 10,000 COP bills. Don't bring 50,000 COP bills; they don't have change.
- Respect the space: Don't leave trash, don't smoke inside the warehouse (unless you see others doing it), and don't touch the sound equipment without permission. These spaces are borrowed, and if something gets damaged, the collective could lose the venue forever.
- Know the signals: Graffiti with codes is the navigation system. For example, a circle with a horizontal line inside (which looks like an "Ø") painted on a corner indicates there's an event that night. An arrow pointing down on a pole means "entrance through the back alley." If you see a red X, the event was canceled or the police found out about it.
Historical context: from factories to sound factories
To understand why Castilla is today a hotbed of experimental music, you have to look back. Between 1940 and 1990, this neighborhood was the epicenter of Medellín's textile industry. Companies like Coltejer, Fabricato, and Tejicondor employed thousands of people, mostly women, who lived on the nearby hillsides. The sound of looms and sewing machines was the daily soundtrack. But the economic opening of the 90s and Asian competition led to the mass closure of factories. By 2005, many warehouses were left empty, with rusted machinery and collapsing zinc roofs.
In the last decade, artists and musicians began to occupy these spaces, not as art galleries, but as sound laboratories. The first collective to do so was Ruido de Taller, which in 2019 organized a party in a warehouse on Calle 89 with borrowed speakers and a diesel generator. The idea was simple: use industrial sounds as raw material. Little by little, other groups joined, and today there are at least five active self-managed spaces. The curious thing is that many of the musicians are children or grandchildren of textile workers, and they see this scene as a way to reconnect with the neighborhood's memory. In an informal interview I had with a Motores DJ in March 2026, he told me: "My mom worked at Coltejer. When I sample the noise of a sewing machine, it's like I'm giving her voice back."
Frequently asked questions
Is it safe to go to these events in Castilla?
It depends on the time and company. Castilla is not a dangerous neighborhood compared to other areas of Medellín, but the inner streets can be dark and empty after 9 p.m. It's advisable to go in a group of at least three people, leave before 1 a.m., and not carry visible valuables. The events themselves are safe because the collectives know the attendees and there is an atmosphere of trust. If you go alone, introduce yourself to the organizer upon arrival and tell them you come recommended by Malokal; that helps.
Can I come if I don't speak Spanish?
Yes, but with limitations. Most musicians and attendees speak Spanish and some basic English, but the rap lyrics and event instructions are usually only in Spanish. If you don't understand, look for someone with a notebook (like at the Frente Rapero) or use gestures. At Ruido de Taller and Motores events, the music is instrumental or experimental, so language is not a barrier. That said, learn at least "¿dónde es la entrada?" and "gracias" in Spanish.
Do I have to pay to enter all events?
No. Motores and Frente Rapero Castilla events are free (although Motores asks you to bring food or a flashlight). Ruido de Taller charges between 10,000 and 15,000 COP, and sometimes asks for voluntary contributions. None accept cards, so bring cash. If an event asks for more than 20,000 COP, it's probably not part of the self-managed scene and is a commercial imitation.
How do I know if an event is still active in April 2026?
The scene changes quickly. The best thing is to follow Ruido de Taller on Instagram (look for them as @ruidodetalher) and the Frente Rapero on Facebook (as "Frente Rapero Castilla"). Motores has no social media, but you can ask at La Esquina del Chicharrón or Panadería El Obrero. You can also check the lampposts on Avenida 65 between Calles 85 and 98: if you see a new graffiti with a QR code, scan it. If nothing appears, it means the event was canceled or moved. In April 2026, Motores events have been irregular due to construction in the area, so check a week in advance.
