Charles Cohen is one of the American pioneers of live synthesizer performance, an improviser known for his mastery of the Buchla Easel synth. Cohen has been active since the 70s, but it was only recently that his works were brought to a wider audience thanks to Rabih Beaini (aka Morphosis) and his label Morphine. A series of albums based on older works and a retrospective compilation put Cohen's abstract sounds in the spotlight, paving the way for a brand new LP - 2015’s "Brother I Prove You Wrong". This renewed interest also resulted in a new creative relationship, as Beaini (also known as Morphosis) helped produce the new material and has became Cohen's live collaborator. Cohen will play solo at Unsound, as well as with Beaini.
