A chopped-and-screwed love letter to the sounds of rebajada – half-speed cumbia, pioneered by Sonido Dueñez in the 1990s, and born from an overheated turntable motor that didn’t make the crowd stop dancing. With Debit’s treatment, rebajada becomes an ethereal, at times intense ambient tapestry that’s also a history lesson.

Spend any amount of time pacing the streets of Monterrey, the bustling city in the north of Mexico where Delia Beatriz, aka Debit, grew up, and you’ll be sure to catch traces of cumbia echoing from Bluetooth speakers, DIY soundsystems, or car stereos. An Afro-Latin dance form and »practica cultural« originating in Colombia in the early 19th century, cumbia evolved rapidly in the early 1900s, as a localised sound played on drums and flutes quickly modernised to integrate European instrumentation like the accordion. When it reached Mexico in the 1940s, the sound shifted again, fusing with mariachi styles and integrating further vallenato folk elements. Eventually, cumbia spread across the entirety of Latin America, splintering into a spectrum of different musical styles such as chicha in Peru, and cumbia villera in Argentina. And over in Monterrey, cumbia inadvertently found its own idiosyncratic groove.

From the 1950s to the 1970s, waves of immigrants from across Mexico and Latin America headed to Monterrey to find work, making a home in Colonia Independencia. Colombian cumbia records, shipped in from Mexico City, Houston, and Miami, became the soundtrack of the neighbourhood, relaying familiar stories to a rural working class adjusting to their new industrial reality. The sound struck a chord with locals, and huge street parties hosted by ramshackle soundsystems known as sonideros unified the diverse community. So when cumbia rebajada materialised serendipitously in the 1990s, it emphasised and highlighted the memory distortions at the heart of the immigrant experience. Local record collector, selector, and sonidero Gabriel Dueñez had been playing cumbia for hours one night when disaster struck: his turntable’s motor overheated and slowed down, turning the music into a warped groan, with half-speed voices echoing over wobbly accordion drones and splashy drums. But the crowd kept dancing, and Sonido Dueñez realised he’d struck gold – cumbia rebajada was born.

Over the next few years, he dubbed a popular series of mixtapes, hawking them at the flea market on the dried-up Santa Catarina riverbed beneath El Puente del Papa, the bridge that links downtown Monterrey with Independencia. These woozy archives became the stuff of legend, poetically but subconsciously shadowing DJ Screw’s series of epochal cassettes that appeared over the border in Houston. Beatriz uses Sonido Dueñez’s first two tapes as the starting point for »Desaceleradas«, entering into a dialogue with time, culture, and geography as she recalls the sonic ecosystem that surrounded her decades ago, long before she emigrated to the USA. If 2022’s acclaimed »The Long Count« was an attempt to recover concealed pre-Columbian history in the face of colonisation, »Desaceleradas« jumps forward, figuring out how memory and shared celebration can resist a more contemporary form of cultural erasure. As AI systems scrape, blend, and decontextualise culture around us, leaving vapid slop, »Desaceleradas« proposes a slower, more careful, and ultimately more human kind of engagement. It’s an archive with a pulse.
