Long before Justin Timberlake discovered a suit and tie, Michael Bublé was wearing them as part of his Vegas-y crooner act — except his outfit was from the thrift shop. Now that he's headlining arenas and scoring with such original tunes as "Haven't Met You Yet" and "Home," Bublé can afford designer threads to go with his slick-and-suave big-stage presentations of songs associated with Frank Sinatra, Van Morrison and the Bee Gees. (8 p.m. Wed., Xcel Energy Center, $56.50-$112.) Jon Bream
FESTIVALS
One of the few local acts to graduate from sold-out, multi-night stands at First Ave to one big gig outside the Cabooze, wise-acre indie-rap star Prof wasn't kidding around when it came time to assemble a festival-like lineup for his to-do. He's bringing in unlikely but successful partners Killer Mike and El-P, who will perform as a duo behind their wigged-out new album "Run the Jewels," along with playful California wordsmith Fashawn, who was Prof's traveling companion on the Road to Paid Dues tour. From the local scene, look for the Get Cryphy DJs and a bunch of Prof's fellow South Siders, including MaLLy, Tony Bones, Big Wiz and Mike the Martyr, plus some not-so-surprising surprise guests. You can bet Prof will be at his boldest and bawdiest, too, having healed up from knee surgery after years of playing a madman on stage. (4 p.m. Sat., Cabooze Plaza, all ages, $20.)

One of the best annual events at one of the best outdoor venues in town, St. Paul's Concrete & Grass Festival boasts another diverse lineup of local talent. On Friday, Velvet Lapelles bandleader Lucy Michelle will play from her classic-pop solo album with help from New Standards bandmates John Munson and Chan Poling, who co-produced the record, and opening support from worldly dance band Marimba Africa and one act TBA. Electronic whir-rock favorites Halloween, Alaska headline Saturday with members of the Minnesota Opera, McNally Smith College of Music's Sphericals and the Copper Street Brass Quintet. (5-10 p.m. Fri., 4-10 p.m. Sat., Mears Park, 221 E. 5th St., downtown St. Paul, free.) Riemenschneider
Attendees of this year's Summit Backyard Bash had better pace themselves, as the 2013 lineup merits spending the entire day at the brewery. On tap to top out the event is the Secret Stash Soul Revue, featuring some of the R&B/soul vets from last year's "Twin Cities Funk & Soul" compilation, preceded by Haley Bonar and her electrifying new band; jazz-pop cover-song maestros the New Standards; the Chalice's soulful rapper Lizzo backed by Doomtree's Lazerbeak; Domino Records' own psychedelic Minneapolitan gang Night Moves, and acoustic roots hero Charlie Parr with friends. Proceeds benefit the Minnesota Music Coalition, promoting local musicians around the state. (Noon-8 p.m. Sat., Summit Brewery, 910 Montreal Circle, St. Paul, 21 & older, $18-$20, SummitBrewing.com.)

POP/ROCK
The Afro-European-soul exotica of Les Nubians is on full display on "Nu Revolution," the French-Cameroonian sister duo's ambitious 2011 album. Helene and Celia Faussart offer ballads, trip-hop, spoken word, hip-hop/soul, dance music, Afropop, jazz, traditional African music, Prince-influenced funk and Euro-soul. (7 & 9 p.m. Fri., Dakota Jazz Club, $35-$40.) Jon Bream
We can accept Journey with a new singer because Steve Perry essentially retired. But if you want to know what Foreigner is, it's founding guitarist Mick Jones' band without lead singer Lou Gramm, who performs "Jukebox Hero" and "Hot Blooded" under his own name on the road. Meanwhile, Jones continues to tour with Foreigner and lead vocalist Kelly Hansen, a member since 2005. Jones' group will be joined by 25 members of the Shakopee High School choir on "I Want to Know What Love Is." (8 p.m. Fri., Mystic Lake Casino, $49-$59.) Bream
The Twin Cities' most successful metal band of all time, American Head Charge is back after a two-year hiatus and one very tumultuous decade before that. In that time, the industrialized thrashers recorded their sophomore album, "The War of Art," with mega-producer Rick Rubin but then succumbed to personal demons and music-industry woes. Founding bassist Chad Hanks and vocalist Cameron Heacock re-formed the band last year with longtime guitarist Karma Cheema and drummer Chris Emery in tow. They have a new EP, "Shoot," which includes the Alice in Chains-like single "Sugars of Someday," alongside a raw cover of Patti Smith's "Rock 'n' Roll N****r." Their summer tour finale is stacked with four boisterous local openers, including Blue Felix and Throw the Fight. (9 p.m. Fri., First Avenue, $20-$25.) Riemenschneider
The Indigo Girls, the folk-rock duo with many righteous causes, will headline an Honor the Earth benefit in St. Paul. Amy Ray and Emily Saliers will do an acoustic set, activist Winona LaDuke will speak and Lyz Jaakola and Neeconis Women Singers also will perform. (8 p.m. Sat., the O'Shaughnessy, St. Catherine University, $30-$35.) Bream
