Devon Allman, Duane Betts and Berry Oakley Jr. talked about playing in a band together for almost three decades. But their respect for The Allman Brothers Band, the Southern rock institution their fathers (and uncle) formed in 1969, stopped them.

When the three met in 1989, The Allmans had just reunited (though Oakley’s father, bassist Berry Oakley, died in a motorcycle crash in 1972). The reunion kicked off a second life that lasted until 2014, when new guitarists Warren Haynes and Derek Trucks (nephew of drummer Butch Trucks) quit.

“We ditched school to go out on the ’89 tour, the reunion tour,” said Devon Allman, son of Allman Brothers frontman Gregg Allman and nephew of original lead guitarist Duane Allman, who also died in a motorcycle crash a year before Berry Oakley, in 1971.

“And that was really when The Allman Brothers were putting back together their fan base and getting back out there and winning the fans over again and getting their s— together. I think that in the music industry at large, they made such a massive statement, and they’re so near and dear to their fans hearts that it’s really hard to get the three of us to collaborate while that band is living and breathing. I think the respectful thing to do was to wait until the band was retired.”

Though it took a little longer than that, the three musicians are finally making music together in their own band, The Allman Betts Band. When Devon spoke to GO! Magazine, he and the new, seven-piece outfit were putting the finishing touches on their debut album at Muscle Shoals Sound Studio in Alabama, where The Rolling Stones, Aretha Franklin, Lynyrd Skynyrd, Bob Seger and more recorded. The album is due out in the spring, and the band will launch its first tour in March.

But before that, Devon and Duane, son of Allmans guitarist Dickey Betts, have some unfinished business with their joint tour, which has kept them on the road most of this year. The final leg of the tour, which features many of the same musicians in The Allman Betts Band (as The Devon Allman Project), lands at the Tower Theatre on Tuesday.

Past shows on the tour have opened with a 30-minute set from Duane performing with slide guitarist Johnny Stachela and The Devon Allman Project’s rhythm section, followed by The Devon Allman Project tackling songs from Devon’s blues-rocking band Honeytribe, supergroup Royal Southern Brotherhood and his solo albums. The duo join forces during the encore, which features Allman Brothers deep cuts and other covers (past shows have featured their takes on Prince and The Cure).

Bend and the rest of the tour will probably follow the same format, but fans can expect a different experience with the new ABB on the horizon.

“This is a very cool time to see the band because this is the transition,” Allman said. “So we’re gonna start sneaking in songs from the new record; we’re gonna start playing some new cover songs. And the show is going to — essentially from this point until March it’s going to morph into what will become The Allman Betts Band. So, people are gonna see it happen right onstage as it happens.”

Devon, who forged his musical career in heavy, Chicago-style blues rock in the ’90s and 2000s, took a year off from playing and touring after his mother and father died in 2016 and 2017, respectively.

“This year was about me getting back out there,” he said. “I wanted to definitely pay homage to my father and play a couple of his songs, and then, I wanted to feature Duane.”

Duane recently left the touring lineup of Los Angeles folk-rockers Dawes and dropped his first solo EP, “Sketches of American Music,” earlier this year. The record led Devon to invite Duane out on the tour, which in turn led to the The Allman Betts Band.

“I heard Duane’s EP and I was like, ‘Man, your songwriting really went to the next level,’” Devon said. “And he goes, ‘Well, man, this guy Stoll Vaughan, he’s worked with Mellencamp; he’s just a really good writer.’ And I said, ‘Well, we’ve got an extra bunk on the bus; why don’t you bring Stoll out and let’s see if we can come up with some stuff?”

Devon and Duane worked out new songs with Vaughan in three different sessions on the road.

“I can honestly say there’s just a lot of Derek and the Dominos feel (in the music); there’s a deep R&B feel on a couple (of) tracks; there’s a deep Nashville or Texas kind of feel as well,” Devon said. “It sounds familiar and fresh all at the same time, and we’re really proud of it. That process took the whole summer; it happened backstage, on the tour bus, hotel rooms. The three of us would just sit with three legal pads and three acoustic guitars and just let it rip.”

Grammy-winning producer Matt Ross-Spang (Jason Isbell, Margo Price) worked with the band, which features Devon, Duane, Berry Oakley Jr. on bass, Stachela, and Devon Allman Project percussionists R. Scott Bryan and John Lum. The record also features cameos from Rolling Stones keyboardist Chuck Leavell and former Gregg Allman Band keyboardist Peter Levin.

“They haven’t done a record at Muscle Shoals since The Black Keys did a record (2010’s ‘Brothers’) there a few years ago,” Devon said. “We’re really honored to add to the history of the whole deal.”

Beyond next year, Devon said he and Duane may continue to pursue their solo careers (Devon released his third solo album, “Ride or Die,” in 2016) on the side, similar to Allman Brothers side projects such as The Gregg Allman Band and Haynes’ Gov’t Mule. But The Allman Betts Band is in it for the long haul, he said.

“I think it’s our turn now not only to collaborate and make some music,” Devon said. “That’s the whole thing. The three of us can get together and play, and we can play a few of our dads’ songs, but if we don’t have something — something real that we can hang our hats on that’s our own — then it’s kind of like, what’s the point?”
