The first informal jam by the musicians who would become The Allman Brothers Band kicks off the 10 LP/5 CD set Trouble No More: 50th Anniversary Collection, that Island Mercury/UMe will release 2/28.

The demo from that jam in 1969, on Muddy Waters’ “Trouble No More,” is one of seven previously unreleased tracks in the set; a live performance of “Trouble No More” from the Allman Brothers Band’s final show at New York’s Beacon Theatre closes the collection.

Arranged chronologically and thematically and representing all 13 of the band’s lineups, the set is divided by the group's stints on the Capricorn, Arista and Epic labels, as well as the band's own Peach imprint.

Both editions include a 9,000 word essay on the band by John Lynskey, unreleased band photos and a recap of the 13 incarnations of the band lineup. All recordings have been newly mastered by Jason NeSmith at Chase Park Transduction in Athens.

The surviving members of the Allmans will be performing a 50th anniversary concert at Madison Square Garden on 3/10.
