They combine three electric likembé (a traditional instrument similar to the mbira) with voices, dancers, and percussion instruments that are made out of items salvaged from a junkyard. The group’s amplification equipment is equally rudimentary, including a microphone carved out of wood fitted with a magnet from an automobile alternator and a gigantic horn-shaped amplifier.
The above track (if you’re reading via RSS click here), Kule Kule, is a collaboration with Jherek Bischoff and is one of the most supremely wonderful things to fill my ears in quite some time. If Colossal had a soundtrack, this would be on it. Incidentally this is the same track used by Tim Wheatley in his Cyclotrope video. Buy the track off iTunes.
