The official birthdate of The Allman Brothers Band is March 26, 1969, when Gregg Allman returned from a short stint in Los Angeles and joined the rest of the band in Florida to rehearse Muddy Waters’ “Trouble No More.” Four days later, ABB debuted at the Jacksonville Armory.

To commemorate the milestone, the band’s shrine, the Big House in Macon, will open from 11 a.m.-6 p.m. Tuesday with free admission.

As well, SiriusXM’s Jam On channel (29) will premiere the upcoming archival release, “The Allman Brothers Band: Fillmore West” at 2 p.m. Tuesday. Additional broadcasts will take place at 11 a.m. Wednesday, 6 p.m. Thursday, 8 a.m. Friday, 3 p.m. Saturday and noon Sunday.

The premiere will be hosted by the channel’s Stef Scamardo and longtime Allman Brothers Band guitarist, Warren Haynes.

The “Fillmore West” album is due later this year and includes multiple shows by the original lineup – Gregg on keyboards, Duane Allman and Dickey Betts on guitars, Berry Oakley on bass and Butch Trucks and Jaimoe Johanson on drums.
