Celebrating their 50th anniversary, the Allman Brothers Band will put out their previously-unreleased Fillmore West ’71 collection as a four-CD offering on Aug. 16.

Recorded just two months before their historic At Fillmore East, the newly unearthed recording is culled from three gigs (January 29-31) in 1971, featuring hits like “Statesboro Blues,” “In Memory of Elizabeth Reed” and “Whipping Post” as well as covers like Muddy Waters’ “Trouble No More.”

According to a press release, these recordings showcase a “loose and talkative” ABB, and “you can hear them really dialing their sound in at what would be a final tune-up for the seminal At Fillmore East album.”

Check out the tracklist for Fillmore West ’71, and listen to the album’s version of “Trouble No More” (via Rolling Stone) below.
