The group continues to support last October's "The Deep End, Volume 2," which is its second album since original bassist Allen Woody died in 2000. Both albums feature surviving founders Warren Haynes and drummer Matt Abts joined by a roster of superstar bassists.

The "Volume 2" lineup includes Jason Newsted (ex-Metallica), Les Claypool (Primus), Phil Lesh (Grateful Dead), Rocco Prestia, Alphonso Johnson, Jack Casady (Jefferson Airplane), Chris Squire, Dave Schools (Widespread Panic), Tony Levin, Billy Cox, George Porter Jr. (The Meters) and Me'Shell Ndegeocello.

Guests on 2001's "The Deep End, Volume 1" include Flea (Red Hot Chili Peppers), Bootsy Collins (James Brown, P-Funk), Mike Watt (Minutemen, fIREHOSE), Mike Gordon (Phish), Jack Bruce (Cream) and the late John Entwistle (The Who).

"The Deep End, Volume 2" includes a bonus disc titled "Hidden Treasure Volume 2," which houses the tracks "Drivin' Rain"--featuring Metallica frontman James Hetfield on vocals and Claypool on bass--as well as two previously unreleased live cuts, two DJ Logic remixes, and "Weekend with Warren," a short documentary that focuses on Haynes.

Last year's "Rising Low," considered the third installment in the band's "Deep End" series, is a documentary film that captures the making of the two "Deep End" albums. Phish bassist Mike Gordon directed the film, which is available in both DVD and VHS format.
