Excerpts from Roulette concerts by improvising activist guitarist Derek Bailey, with commentary by musician/professor/author David Grubbs (Records Ruin The Landscape). Emerging from the London free improv scene, between 1986-99 Bailey tapped New York musicians to engage in his wildly diverse Company Weeks, in groupings and pairings with John Zorn (sax), Carlos Zingaro (violin), Ikue Mori (electronic percussion), Jim Staley (trombone), Ciro Baptiste (percussion), Jamaladeen Tacuma (bass), Calvin Weston (drums), Susie Ibarra (percussion), Richard Teitelbaum (electronics), and Greg Bendian (percussion). John Zorn is honoring Derek Bailey with three Nights of Improvisation at Roulette, Jan. 19-21, 2023.
