Multi-night gatherings of the tribes abound this weekend, from an Abbey Lounge reunion at Sally O’Brien’s and the 10^th anniversary of music at Atwood’s Tavern to a Dopapod jam-fest at the Sinclair. Plus there’s the return of reggae legend Bunny Wailer (above).

The Abbey Lounge forged its reputation as a dingy Inman Square dive bar where you could catch Boston’s notable punk and garage bands before it closed in 2008. But those loud and wooly nights are being rekindled in a three-night reunion that stretches into Saturday at Sally O’Briens in Somerville’s nearby Union Square. A gang of Abbey favorites will reunite for the celebration. Friday includes the Konks, the Tampoffs, the Dirty Truckers and Frigate, while Saturday boasts the Dents, the Downbeat 5 (both with Jen D’Angora now of Jenny Dee & the Deelinquents), Asa Brebner and aptly named Abbey pioneers Schnockered. Here’s the lineup.

Atwood’s pools its own veteran heavy-hitters with its own special bills. The Tim Gearan Band teams with the Christian McNeill Band on Friday. Saturday starts with the Roy Sludge Trio and Jimmy Ryan’s Hayride in the late afternoon, then dusky, cerebral roots-rockers Twinemen (with Laurie Sargent, Dana Colley and Billy Conway) reunites to open the night with regulars Vapors of Morphine and Mr. Airplane Man. Sunday afternoon brings in Lyle Brewer and Grand Fatilla, while that night closes Atwood’s anniversary week with the Burren’s former Sunday session band plus the Bow Thayer Trio and the Resophonics. Here’s the rundown.

Meanwhile, rising Berklee-schooled jam-rockers Dopapod stretch out their improvisational segues on Friday and Saturday at the Sinclair. And Delta Spirit frontman Matthew Logan Vasquez steps out with his own rocking band at Café 939 while “American Idol” and YouTube-boosted pop singer Tori Kelly (here paying one of the past week’s tributes to Prince) hits House of Blues on Saturday.

But in a sense, the weekend’s biggest event will be the return of Jamaican reggae survivor Bunny Wailer — one of the original Wailers with Bob Marley and Peter Tosh — rolling into the Paradise Rock Club on Saturday as part of his first tour in about two decades. The three-time Grammy winner, now 69, will showcase songs from his 1976 solo debut Blackheart Man on a bill with local groove-droppers Dub Apocalypse. And if that’s not enough, cap off the weekend with Minneapolis-bred punk pioneer Bob Mould, mixing old and new solo work with recharged Husker Du nuggets on a Sunday bill at the Paradise that sports the also-great Ted Leo.
