Hudson, New York-based experimental musician and synthesizer aficionado M. Geddes Gengras has been involved with numerous projects ranging from psych-folk and noise rock to dub reggae and cosmic ambient drone. He became an in-demand collaborator during the second half of the 2000s, participating in experimental groups such as Robedoor and Pocahaunted before he began releasing solo cassettes and CD-Rs of his modular synthesizer improvisations in 2009. Along with close associate Sun Araw (Cameron Stallones), Gengras worked with influential reggae group the Congos on the acclaimed 2012 release Icon Give Thank. He has issued several ambitious long-form drone works, including 2018's double-CD Light Pipe, as well as noisy experimental techno as Personable and under his own name (2020's Time Makes Nothing Happen). 2022's Expressed, I Noticed Silence featured his brother Cyrus Gengras, his former collaborator in the duo Antique Brothers.
