BECHA-KPACHA (pronounced VesnA KrasnA) is an algorithmic music video produced by Jeremy Rotsztain for the electronic musician COH. Riffing on traditional Russian folk patterns the colour-splashed animation is full of Rotsztain’s signature gestural forms and synchronized camera movements. BECHA-KPACHA is an old Russian rhyme. Its title roughly translates as "spring the beautiful" or "spring the red."

BECHA-KPACHA was programmed using openFrameworks. It uses Kyle McDonald’s ofxFFT library for audio analysis and James George’s ofxTimeline for arranging the different visual objects and behaviors. COH provided me with a collection different audio tracks — synthesizer arpeggiators, percussion, bleeps and bass — which were used to trigger and animate various shapes in three dimensional space.
