The moody, robotic sounds of bleep (often referred to as "drill 'n' bass") came out of a resurgence of interest in electro in Manchester in the mid-1990s. Named after the Blip, Bleep: Soundtracks to Imaginary Video Games compilation, a more extreme example of the genre featuring V/VM and Soundcard, the music is a thinly rendered electro sound played with the frenetic abandon of jungle. Led by headphone experimentalists such as Plaid, Autechre and Mu-Ziq, and championed by labels SKAM and Warp, Bleep is far too irregular for the dancefloor yet often too disruptive for passive listening.
