Boris at Last -Feedbacker- (or simply called Feedbacker) is the sixth studio album by Japanese experimental music band Boris. The album, a single 43-minute track broken into 5 movements, incorporates many different rock elements. The band frequently revisits the song in concert.
On September 13, 2009, as a special set for the Flaming Lips-curated All Tomorrow's Parties New York 2009 in Monticello, Boris performed Feedbacker in its entirety. They performed the album again at the Pavement-curated ATP at MineheadButlin's on May 15, 2010. An official DVD, limited to 500 copies, was released in 2005 by Diwphalanx Records. This DVD was originally an unofficial recording of the band performing the entirety of Feedbacker live in New York and entitled Bootleg -Feedbacker-. The official DVD release depicts a different member of the band lying in a pool of blood similar to Wata on the album cover.
Track listing
The obi strip on the Japanese CD release lists only one track despite the track being indexed into five parts on the CD release; otherwise no track listing or timings are given on CD or LP.
On the LP release the track is split into two parts, one on each side. The original Japanese LP as well as the reissue on Third Man Records contains a locked groove on both sides.
