Fifty-seven years ago today, March 26, 1969, Gregg Allman stepped into a rehearsal in Jacksonville and six musicians became the Allman Brothers Band. Today's post marks the anniversary with a reading from Play All Night—plus Derek Trucks on on Jerry Garcia's $12 million Tiger guitar, Tedeschi Trucks Band's banger new album, Warren Haynes pushing back on labels, a pastiche of links, and six episodes of Conversations from the Crossroads.
