Mark Hosler is a founding member of Negativland, the influential experimental music collective that emerged from the San Francisco Bay Area in the late 1970s. As a core creative force alongside David Wills, Peter Conheim, and Jon Leidecker, Hosler has helped shape the band's distinctive approach to sound collage and electronic composition, spanning releases from abstract sonic experiments to more structured musical works.
Negativland's prolific catalog has been primarily released through their independent label Seeland Records, with notable recordings for SST Records including *Escape from Noise*, *Helter Stupid*, and the controversial *U2* album. The band's innovative work in deconstructing and reimagining source material has made them pioneers in experimental electronic music, while their legal battles over copyright and artistic appropriation brought significant attention to issues of creative freedom in the industry.
