Wobbly is the long-running collage project of Jon Leidecker (US), who improvises live with pre-recordings to coax the harmonies out of recorded sounds of individuals and animals from disparate cultures. Albums have been released on the labels Alku, Phthalo, Illegal Art, Tigerbeat6 and Vague Terrain. Previous and ongoing projects include the bands Chopping Channel, Sagan, the Freddy McGuire Show and Amen Seat, as well as various collaborations with Negativland, Matmos, Thomas Dimuzio, Blevin Blectum, Lesser, Tim Perkis & Xopher Davidson, Otomo Yoshihide and MaryClare Bryztwa. In 2009 he was commissioned by the Museum of Contemporary Art in Barcelona to produce “Variations”, a podcast and lecture series overview of the history of musical collage & sampling.
