Avett Brothers & Trampled by Turtles: Either of these rootsy and brotherly bands could play Treasure Island's new amphitheater on their own at this point in their resilient careers, which is proof that they're pairing up there in part just for the fun of it. And the show really should be a hoot, especially at this somewhat out-there but well-equipped outdoor venue. Trampled is the home-turf favorite but is leaving the headlining slot to the poppy yet bluegrassy North Carolina visitors, who touch on the serious news of the day but maintain a hopeful and fun spirit on their new album, "Closer Than Together." (7 p.m. Sat., Treasure Island Casino Amphitheater, 5734 Sturgeon Lake Road, Red Wing, only $79 seats remain, ticketmaster.com.)
Soccer Mommy: Nashville indie rocker Sophie Allison, 22, falls somewhere between Mac DeMarco and Sharon Van Etten with her lo-fi, mellow-cool guitar-heavy tunes and sly lyrical style. She just dropped a cool version of the Dixie Chicks' "Wide Open Spaces" as welcome filler while she works out the follow-up to last year's acclaimed Fat Possum release, "Clean." (9 p.m. Fri., Amsterdam Bar & Hall, St. Paul, $18.)
Michael Feinstein: The cabaret king has been an assistant to Ira Gershwin, prolific recording artist, pops conductor, educator, NPR radio host, proprietor of eponymous nightclubs (New York, San Francisco, Los Angeles) and popular singer/pianist of the Great American Songbook, the role he will play in Minneapolis, on the closing of a two-night engagement. (7 & 9:30 p.m. Fri., Dakota, $50-$90.)
Joseph: The sister trio from Portland, Ore., made a strong impression with dramatic harmonies but fun approach at 89.3 the Current's birthday party in 2012, and now it's back touting its week-old album "I'm Alone, No You're Not," produced by Conor Oberst's Omaha cohort Mike Mogis. (9 p.m. Fri., First Avenue, $25.)
Craig Paquette: The Thunderheads guitarist is stepping out with his first solo album, "Won't Last Forever," a Rich Mattson-produced collection with the obvious but heartfelt Neil Young and Bob Dylan influences. Mattson's Northstars and the Thunderheads also will play the release party. (7:30 p.m. Sat., the Hook & Ladder, $10-$15.)
Ranky Tanky: Thanks to support from NPR's Terry Gross, this South Carolina quintet's self-titled debut made it to No. 1 on Billboard's jazz chart last year. But it would be criminally limiting to consider Ranky Tanky a jazz ensemble. The genre-blending group is rootsy, old-timey yet modern, assimilating elements of jazz, blues, spirituals, R&B, folk, African music, kids' music — you name it. It's all good music, with former "American Idol" contestant Quiana Parler standing out on exciting and uplifting vocals. (7 p.m. Sun., Dakota, $40-$45, dakotacooks.com.)
Andy Grammer: A Twin Cities favorite, this L.A. popster must have been listening to a lot of Imagine Dragons because several tunes, notably the singles "My Own Hero" and "Don't Give Up on Me," on his new album, "Naive," have big, surging choruses reminiscent of ID hits. It's quite a change from "Honey, I'm Good," the radio triumph that first endeared him to local listeners. (6:30 p.m. Sun., Varsity, sold out)
Roadstock '19: Nicollet Avenue's Open Streets fest and this classic south Minneapolis record store's 33⅓ anniversary make a pretty good twofer excuse for this outdoor bash, featuring '60s-flavored guitar pop and garage rock from the Magnolias, the Carnegies, the Silverteens and the Roky Erickson tribute band the Psychedelic Sounds Of ... (11:30 a.m.-4:30 p.m. Sun., Roadrunner Records, 4304 Nicollet Av. S., Mpls., free.)
