Miss the churning sounds of the Allman Brothers Band since that iconic group disbanded two years ago? Of course Gregg Allman and Warren Haynes still dip into that songbook with their own projects. But now the Allmans rhythm section of drummers Butch Trucks and Jaimoe, bassist Oteil Burbridge (last seen with Dead and Co.) and percussionist Marc Quinones are refloating that repertoire with Les Brers, a group also sporting onetime Allmans member Jack Pearson and ex-Chet Atkins associate Pat Bergeson on guitars, singer Lamar Williams Jr. (his dad played bass for the Allmans) and locally spun blues keyboardist Bruce Katz. And they’ll be stirring the pot in their new ensemble (named after the Allmans’ exploratory instrumental “Les Brers in a Minor”) at House of Blues on Friday.

The Kenny Garrett Quintet mines spiritual, explosive jazz on Friday and Saturday at the Regattabar behind its post-bop alto saxophonist leader, who cut his teeth in Miles Davis’ band. But Friday’s also notable on the local rock scene, starting with record-release parties staged as impressive triple bills. If a dark, heavy mash of metal, punk and blues sounds like your bag, catch Rumble champs Worshipper (celebrating their worthy debut Shadow Hymns), Zip-Tie Handcuffs and the Devil’s Twins at Once Ballroom in Somerville. Add spooky, steam-punky mania and you get Walter Sickert & the Army of Broken Toys, who’ve never sounded better than on the Joel Simches-produced Come Black Magic. The Toys share an eclectic bill at the Sinclair with torch-pop vocal standout Ruby Rose Fox (whose own dramatic, much-anticipated recent album Domestic doesn’t disappoint) and Mount Peru.

But wait, there’s more! Juliana Hatfield reunites with John Strohm and Freda Love in their ’90s indie-rock combo the Blake Babies to cap a Saturday block party at the center of Allston’s Awesome Christmas, a merger of the Awesome Day Fest and Allston Christmas Block Party. That outdoor bash, also sporting alt-rockers Weakened Friends and rapper Dutch Rebelle, goes down at Pop Allston—free with RSVP here. But the fun continues Friday and Saturday in the Allston clubs, peaking with a Saturday bill at Great Scott that includes E (blues-punk veteran Thalia Zedek’s edgy new outfit with Neptune’s Jason Sanford and Karate’s Gavin McCarthy) as well as the Sheila Divine, Mini Dresses, Minibeast and Magic Magic.
