Watch Moritz Simon Geist's Sonic Robots Play Thumping Techno Music in His Video for 'Entropy'

When he plays a techno show, Moritz Simon Geist doesn't reach for a laptop. Instead, he calls on his army of sonic robots--a collection of small, motorized creations that click, clank, and whirr in an intricate mechanical symphony. Geist composes robotic electronic music, a burgeoning genre of electro jams that relies on hardware, not software, to engineer electronic sounds and beats. His forthcoming EP, The Material Turn, debuts in October with four tracks made entirely from self-fashioned instruments--futuristic robo-kalimbas, a droning guitar, and salvaged hard drives turned into percussive beat machines. Watching Geist play music is a little like watching a mad scientist in a lab.
