Though they started out on the hardcore rave scene in the early '90s, The Future Sound of London quickly became one of electronica's most experimental acts. While they'll occasionally drop a slamming club anthem, the UK duo are best known for their wildly intricate melodies and shape-shifting rhythms. You can't always dance to this collection of FSOL's unpredictable tracks, but you can certainly get lost in these otherworldly grooves, as the boundary-pushing pair twists house, techno, and ambient music into gorgeous and complex new forms.
