Final Release!! Played by Richie Hawtin & Loco Dice !!! Perc s debut release for ovum recordings, the mathlete ep - title track mathlete is an industrial soundscape. a living, breathing, composition, with a murmuring, metallic heart. percolating bass, delicate mood changing synths, twisted wah-wah guitar and steel drum percussion, all make this moody opener a hit for the floor.
