Close your eyes and imagine a multimedia psychedelic bike ride. Video provides a visual of the urban landscape passing by, synchronized to audio, everything modulated by pedalling. Pedal faster -- the video moves faster and tempo increases. Pedal slowly or brake, and it all slows down. The rhythms, seemingly drums and bass -- are not quite electronic or acoustic. Why? Because every sound originated from a bicycle. Another bicycle provides improvised accompaniment: sounds of the city and of nature, both modulated by the movements of the bicycle and its riders. The third and final bike provides surprise: bass tones from the tires (is this what burning rubber sounds like?) and other sounds of motion.
