The Bad Plus do smart addition with Joshua Redman at Berklee.

If you want to see a live Beatle these days, you can either see Sir Paul ply the hits in a stadium setting or watch Ringo Starr take a more modest, fun approach at a more intimate hall like the Citi Wang Theatre, where the drummer/singer plays  Friday. Besides his Beatles favorites, you’ll get a complementary catalog sampling from his All-Starr Band members, including the wondrous Todd Rundgren, Toto’s Steve Lukather and early Santana’s Gregg Rolie. Also on Friday, Beverly-born post-rock heroes Caspian pack in the faithful at the Sinclair, while sexually frank electro-clash performer Peaches brings her latest show to the Paradise Rock Club.

The next-big-thing at age 21, (she just announced a headlining date at Madison Square Garden for next year), electro-pop singer Halsey strikes a balance between the spunk of Miley Cyrus and the brooding of Sinead O’Connor for a loving horde at House of Blues on Saturday. The same night, the David Wax Museum gives its Mexican-inspired folk more of an indie-pop snap at the Sinclair, Canadian singer/harpist Loreena McKennitt’s trio shares her Celtic folk at the Citi Shubert Theatre, and the 38^th annual John Coltrane Memorial Concert presents “Ornette ’n ’Trane” at the Northeastern Center for the Arts, featuring an all-star local cast that adds pianist Laszlo Gardony and his steady cohorts Stan Strickland, John Lockwood and Yoron Israel.

But Saturday’s most electrifying option looms in Vintage Trouble, the California R&B-rockers who hit the Brighton Music Hall after opening for AC/DC in stadiums. Vintage frontman Ty Taylor crosses James Brown moves with a dash of Bruce Springsteen’s savvy for crowd contact. Then on Sunday, World Music/CRASHarts offers a totally cool jazz supergroup at the Berklee Performance Center with slyly subversive piano trio the Bad Plus and Joshua Redman lending a rich fourth voice on saxophone, while John Doe (co-singer of X) steps out on his own that night at cozy Atwood’s Tavern.
