Using found sounds, tape, feedback, prepared string instruments, field recordings, and hybrid analog / digital systems, Geoff Mullen combines improvisation, post-industrial ambient music, and site-specific sound-installation. As a solo artist, he has toured throughout the US, Canada, and Europe, and is a frequent collaborator with percussionist / composer Eli Keszler. Since 2008, he has worked alongside Keith Fullerton Whitman at Mimaroglu Music Sales, and he is the founder of Rare Youth – an independent record label dedicated to the support of local experimental music.
