A feature-length documentary on Jay Bennett, a legendary musician and recording studio savant, who as a member of Wilco, was a large part of the genius behind their three seminal albums (Being There, Summerteeth, and Yankee Hotel Foxtrot -- he co-wrote most of Summerteeth and YHF with Jeff Tweedy), as well as the Mermaid Avenue/Woody Guthrie sessions with Billy Bragg. Bennett went on to a critically acclaimed solo career, before dying tragically at the age of 45.
