Double up: Five surprising production collaborations we're delighted happened

While Ricardo Villaobos and Butch share some stylistic similarities, there’s a spectrum of floor functionality between them, so the outcome of these two working in tandem was always going to be intriguing. The result was more of a chaotic mindfuck than we could ever have anticipated. ‘Up’ from the duo’s 2013 EP on Sei Es Drum is one of the most playful, frustrating, humorous and tantalising records in memory. It surges to the sky, powering towards a drop that never comes. If you’ve ever heard this one in a club you’ll know the jarring impact it has, as hands raise and bodies tense in anticipation, but the track just keeps rolling up. It’s pure dancefloor confusion and eccentricity.
