Bayfront Blues Festival: Now in its 31st year, this three-day Duluth event emphasizes quality live acts over big names. Friday's headliner is Bobby Rush, the 85-year-old Blues Hall of Famer who won his first Grammy in 2017 and has worked with Elmore James, Muddy Waters, Jimmy Reed and so many other greats. Headlining Saturday is Serbian-born blues guitar sensation Ana Popovic while the Kentucky Headhunters, those veteran Southern rockers with a flair for humorous country tunes, close out Sunday's schedule. Among the many other performers are Ken Valdez, Sena Ehrhardt & Cole Allen, Joyann Parker, Lamont Cranston and Reverend Peyton's Big Damn Band. (11:30 a.m. Fri.-Sun., Bayfront Park, Duluth, $50 and up, bayfrontblues.com)
Gary Clark Jr.: What a difference a year has made since his sizzling show at the same venue last summer. The Texas blues rocker released his most varied yet definitive album yet, "This Land," which shows there's a lot more to the Austin native than his genuinely awesome, Stevie Ray Vaughan-like guitar-hero skills, as he easily slides between the Prince-influenced slow groover "Pearl Cadillac" to the punk-rocky "Gotta Get into Something" to the bombastic, racially outraged title track. (6:30 p.m. Fri., Surly Brewing Festival Field, 520 Malcolm Av. SE., Mpls., sold out.)
Gladys Knight: Even though she's playing in a casino, seeing the Empress of Soul is no gamble, judging by how she tore it up last fall at the Ordway in St. Paul. Part sermonizing preacher, part chatty neighbor and all sanctified soul singer, she has a jukebox full of gems, including "I Heard It Through the Grapevine" and "Midnight Train to Georgia." (8 p.m. Fri.. Mystic Lake Casino, $39 and up)
Lady Midnight: The dog days of summer seem like the perfect time for this Twin Cities neo-R&B singer to release her rhythmically chill but musically and lyrically sultry debut solo album, "Death Before Morning." After her attention-grabbing collaborations with P.O.S. and Bon Iver, the full-length LP confirms her unique ability to deliver ethereal, soothing vocals with deep soul and power, with traces of Sadé and even Nina Simone over modern, innovative electronic grooves. It also nods to her Afro-indigenous roots along with a strong visual component via both music videos and her live show. Ziyad, Boo Boo and DJ Keezy will help her celebrate. (9 p.m. Fri., Turf Club, 1601 University Av. W., St Paul, $12-$15, eTix.com.)
Bruce Hornsby: Friend of the Grateful Dead and Bon Iver, the adventurous piano man brings his Noisemakers to showcase his daring new album, "Absolute Zero," featuring collaborations with Dead lyricist Robert Hunter, Bon Iver's Justin Vernon and filmmaker Spike Lee. Opening is Bon Iver drummer/singer S. Carey, who also played on the album. Read an interview with Hornsby at startribune.com/music. (8 p.m. Fri., Pantages Theatre, Mpls., $68-$78)
Brewer and Shipley: These harmonizing Vietnam War-era folkies are best remembered for their 1970 classic "One Toke Over the Line," perfect for these pro-pot times. (8 p.m. Fri., Cedar Cultural Center, Mpls., $20-$25)
Queen + Adam Lambert: Movies have enabled Queen to enjoy a great afterlife. First, it was "Wayne's World" in 1992, reviving the hit song "Bohemian Rhapsody." Last year, it was the biopic "Bohemian Rhapsody," reviving the life of late singer Freddie Mercury. Bigger than ever, Queen is back on tour with original members Brian May on guitar and Roger Taylor on drums, and vocalist Lambert, the campy, glam "American Idol" runnerup who is fulfilling his destiny. (8 p.m. Sat., Xcel Energy Center, St. Paul, sold out.)
Grand Country Night: It's a day-long twang fest headlined by the great Hollywood honky-tonker Dwight Yoakam, he of those crazy legs, along with the rebounding Billy Ray Cyrus of "Achy Breaky Heart" and now "Old Town Road" fame, deep-voiced hitmaker Josh Turner and southern rockers .38 Special. (1 p.m. Sat., Grand Casino Hinckley, $79-$109)
