HIP-HOP It might seem like old news having a hometown rapper pack First Ave two nights in a row, but Brother Ali's latest stand will offer several firsts: It's his first local showing since last month's release of his provocative, topical, seething new album "Mourning in America and Dreaming in Color." For most local fans, it will be the first chance to hear him with his new, horn-blasting live band, Blank Tape Beloved. Saturday's all-ages show will also feature local high-schoolers who competed to open. New York indie-rapper Homeboy Sandman and Denver duo the Reminders also perform each night. Read a new interview with Brother Ali at startribune.com/music. (9 p.m. Fri. & 6 p.m. Sat., First Avenue. $15. Fri. show sold out.) Chris Riemenschneider
With Ali busy on tour, his partners in rhyme, Atmosphere, are taking over the Twin Cities Day of Dignity block party, which Ali helmed last year to help tornado- and economy-ravaged North Side residents. Slug and the band will play a rare free set along with Ohio rapper and Rick Ross protégé Stalley of the Maybach Music Group. Free clothes, food and health care will also be on hand for those in need. The event is partly intended as an open house for north Minneapolis as well as the hosting mosque, so truly everyone is welcome. (11 a.m.-6 p.m. Sun., Masjid An-Nur, 1729 Lyndale Av. N., Mpls. Free.)

POP/ROCK After more than 25 years in Nashville, Michael Johnson has moved back to Minnesota, where he lived during his "Bluer Than Blue" days. He's celebrating his first studio album in 17 years, "Moonlit Déjà Vu," recorded for St. Paul's Red House label. It features a duet with Truly Carmichael, his daughter who was given up for adoption but with whom he recently reconnected. Coincidentally, she moved to the Twin Cities this year and will sing at his concert. Read an interview with them at startribune.com/music. (8 p.m. Sat., Hopkins Center for the Arts, $24.) Jon Bream
Gossip's Beth Ditto remains one of rock's most compelling frontwomen, an unlikely combo of Karen O, Grace Jones and a punk-rock Adele. She's a dynamo onstage, so no wonder the Arkansas native has been pushing her Portland, Ore.-based band and their fans in a get-up-and-move direction with a series of more dance-oriented albums, including the riotous new one "A Joyful Noise." Oregonian soul-pop band Magic Box and Arkansas twang-opera singer Bonnie Montgomery open. (9 p.m. Sat., Fine Line. $20.) Riemenschneider
Over five albums, North Carolina native Tift Merritt has proven to be a superior songwriter, an effective vocalist and an Americana artist to be reckoned with. Dubbed by critics as the Emmylou Harris of her generation, Merritt, 37, goes the spare and understated route on this fall's "Traveling Alone," a quietly compelling collection infused with poetry, emotion and sweet instrumental seasoning courtesy of ex-Minneapolis pedal steel guitarist Eric Heywood and guitarist Marc Ribot. Underrated Twin Cities singer/songwriter Ben Weaver opens. (8 p.m. Sat., Cedar Cultural Center, $18-$22.) Bream
Like David Byrne and St. Vincent, Norah Jones is kicking off her tour in Minneapolis. Backed by a quartet, she's promoting her Danger Mouse-produced "Little Broken Hearts," a breakup album that shatters the notion of her as a coffeehouse jazz singer. He surrounds her in atmospheric and electronic sounds that sometimes stifle the emotional power of her voice. But the haunting twangabilly title cut, the eerie "Miriam" and the spare, cutting "She's 22" prevail. Wisconsin's Cory Chisel opens. (7 p.m. Sun., Orpheum, $55-$65.) Bream
California punk hero Mike Watt is back to his old ways, blasting through 30 short-burst songs in 47 minutes on his latest solo album, "hyphenated-man." The bassist for the Minutemen and later fIREHOSE made the so-called "punk opera" with his road crew the Missingmen, which features guitarist Tom Watson and drummer Raul Morales and recalls those earlier bands. They're on tour with Lite, a Japanese instrumental quartet that recently recorded with Tortoise's John McEntire. (9 p.m. Sun., Turf Club. $13.) Riemenschneider
The Sheepdogs have been facing an uphill credibility battle since winning Rolling Stone's "Choose the Cover" contest in 2011 and getting made up in an uncomfortable episode of "Project Runway." (Best line: "It looks like something an old lady would wear.") They're better than you think, with a soulful, tight, hard-rock boogie that might qualify them as Canada's best Southern rockers since the Band. Or at least give them the benefit of doubt on this great triple bill with Belgian stoner-rock duo Black Box Revelation and the Buffalo Killers, a Cincinnati trio that formed out of the dissolution of Thee Shams and made their last record with Dan Auerbach. (8:30 p.m. Sun., 7th Street Entry. $15.) Riemenschneider
