Jon Leidecker has been producing music under the name Wobbly since 1990, improvising with recordings to produce music which inherently resist the act of being captured. Recent performances deploy a battery of mobile devices driven by their built-in microphones, reacting instantly with error-prone variations on the notes and sounds they believe they are hearing: a tightly-knit orchestra with inhuman reflexes, resulting in structures which the human performer influences more than controls. Your phone is a musical instrument, and your phone is always listening. Leidecker’s solo performances are complimented by extensive live and studio collaborations, including work with Dieter Moebius & Tim Story, Matmos, Fred Frith, John Oswald, Thomas Dimuzio, Huun-Huur-Tu, Sagan and the Freddy McGuire Show. He recently became a full time participant in the culture jamming art collective Negativland, and as of last year inherited the stewardship of their legendary, long-running live mix media collage program Over The Edge on Pacifica KPFA FM in Berkeley.
