He collected nine Grammys before scoring a big pop hit. Now John Legend is finally a household name, thanks to the chart-topping ballad "All of Me," which could be the wedding song of 2014. Indeed, he performed it at the recent nuptials of Kim Kardashian and Kanye West, who discovered Legend. The hardworking romantic returns for an acoustic evening — his grand piano, string players and an acoustic guitarist — of creamy, dreamy soul-pop. (8 p.m. Fri., Mystic Lake Casino, sold out.)

The Old 97's have too much fun together to ever call it quits, even when frontman Rhett Miller went solo in a not-so-fun adult-contemporary way. Still, there's a comeback/reunion vibe to the Dallas twang-rockers' first record in four years, "Most Messed Up," full of the barn-burning, barroom-dazed story songs that defined the quartet's early albums. The guest appearance by Tommy Stinson fits in perfect with the album's bleary eyes and bleeding fingers. Bluesy St. Louis band Kentucky Knife Fight and Dallas singer/songwriter Madison King open. (9 p.m. Fri., First Avenue, $20.) Chris Riemenschneider
When Bruno Mars thrilled a sell-out crowd at Xcel Energy Center last July, he was clearly the biggest broad-appeal male pop star to come along since Justin Timberlake. Two more hit songs and a Super Bowl halftime performance later, he's bigger than ever. Watch him sing, dance, drum — do it all. Plus, the 28-year-old has written and produced hits for Travie McCoy, B.o.B. and CeeLo Green when he's not busy with his own music. Opening is Aloe Blacc, best known as the voice of the Avicii global hit "Wake Me Up." (8 p.m. Sat. Xcel Energy Center, $45-$102.) Bream
In the 12 years since their last Twin Cities gig, Nick Cave & the Bad Seeds have rearranged their lineup — guitarist Mick Harvey is gone, most notably — but the Aussie rockers haven't lost their dark luster. In concert, they make a strong case for last year's underrated if a bit drab album, "Push the Sky Away," while adding interesting textures to such classics as "Tupelo" and "Red Right Hand." Of course, Cave himself — last seen in town tearing up First Ave with Grinderman— remains one of rock's most electrifying and engaging frontmen. Los Angeles' slow-humming, ethereal rock quartet Warpaint opens. (8 p.m. Sat., State Theatre, sold out.) Riemenschneider
After taking a rare hiatus in 2012, Widespread Panic celebrated its 25th anniversary last year on a tour that played the Orpheum Theatre. But this great jam band belongs outdoors. It'll be joined by a commendable lineup that includes New Orleans' funky jammers Galactic, Conspirator (a Disco Biscuits spinoff), Colorado singer/songwriter Jerry Joseph and hard-charging Minnesota bluegrassers Pert Near Sandstone. (4:30 p.m. Sat., Somerset Amphitheater, $25-$54.50.) Bream
If you can't afford or don't appreciate this year's Rock the Garden lineup, there's another bash Saturday with some of Minnesota's best indie-rock acts in one of the state's coolest outdoor venues: Mankato's fourth annual Arts by the River Festival features elegant chamber-rock faves Cloud Cult along with last year's most memorable RTG performer, Low, and Wisconsin's ambient twangers Field Report. (5-10 p.m. Sat., Vetter Stone Amphitheater, Mankato, free, ArtsBytheRiver.com) Riemenschneider
A few months ago on the Experience Hendrix tour, Jonny Lang tore it up doing songs Jimi made famous. Now the Fargo-born, Minneapolis-launched guitar hero is back to play his own tunes, including "Lie to Me" and "Red Light." Perhaps he'll preview the new blues-rock album he's working on — an overdue return to the sound that made him famous. Nashville's funky Jonny P opens. (7:30 p.m. Sat., Minnesota Zoo, $65-$77.50.).

The Jack Brass Band stands out no matter what it does, since it's the Twin Cities' only New Orleans-styled, second-line-ready brass ensemble to make a name for itself in the Crescent City. With its latest album, "For Your Body," the seven-man party machine sets itself up as even more of an anomaly, blowing out a fun blend of sexy R&B standards ranging from Usher's "There Goes My Baby" and R. Kelly's "Freaky in the Club" to more vintage fare like Carl Carlton's "She's a Bad Mama Jama" and Mel Walter's "Got My Whiskey." As if to show the JBB can hang with the rest, though, the collection ends with a far more obvious but no less enjoyable tear through the Meters' "They All Asked for You." Gypsy jazz ensemble Lulu's Playground opens the release party. (11 p.m. Sat., Icehouse, $6-$8.) Riemenschneider
