Rova Channeling Coltrane is a duet of films on the Rova Saxophone Quartet's reincarnation of John Coltrane's Ascension, called “the most vexatious work in jazz history.” First, in Cleaning the Mirror, we learn the history of the project and hear from the musicians—including Nels Cline, Hamid Drake, and Rova leader Larry Ochs—about their approach to the music. Then, Electric Ascension documents in its entirety a performance of the reimagined album, giving audience members the rare opportunity to see and hear the work performed live. Q & A with Larry Ochs
