The debut release by Colorist is an ongoing compositional project based in Chicago, developed piece-by-piece in an honest and improvisational way. The community explores current hybrid musical territory, concerned with structure and intuition. Charles Rumback and Charles Gorzcynski have performed live duo sets with saxophones, percussion, and electronics. Their new album Lists delves farther into programming and collaboration, welcoming engineers Brian Bullard and Matthew Gagnon into the group, as well as guest bassists Matt Lux and Jason Ajemian, cellists Ellen O'Hayer and Sarah Biber, bass clarinetist Jason Stein, guitarist Bill Mackay, as well as Erhu and mastering by Josh Eustis. Lists is a mixture of repetitive sax and synths, organic drums and percussion, ranging stylistically from avant-jazz and improvised music to post-rock.
