The studio has been the instrument used to produce the bulk of our popular music for over a half-century, yet it is an instrument which stubbornly resists being brought onto the concert stage. Even as software makes studio techniques available to live improvisers, it obscures the process and disconnects the performer's movements from the resulting sounds. Improvising entirely with pre-recorded sounds like a DJ with several thousand turntables, Wobbly has been the inadvertent psuedonym of Jon Leidecker since 1990, and he still performs live without a laptop so you can actually see what he's doing. A recording is different every single time it's played back, and for both performer and audience, music only exists in the instant that you're listening. Wobbly has released albums on Illegal Art, Phthalo, Tigerbeat 6, and Important. He has collaborated and recorded with Matmos, People Like Us, Thomas Dimuzio, Anne McGuire, Negativland, Tim Perkis, Antimatter, Blevin Blectum, Lesser, Otomo Yoshihide, Zeena Parkins, MaryClare Brzytwa, Hrvatski and Huun-Huur-Tu. He is also gradually updating the eight episode online podcast on the history of collage music 'Variations', commissioned by the Museum of Contemporary Art in Barcelona.

Wobbly performed at the Fourteenth Annual Activating the Medium Festival in 2011.
