POP/ROCK
Has Coldplay finally achieved its U2-like ambitions? Well, the British quartet isn't playing stadiums, but Chris Martin and company are wrapping up a hugely successful North American tour with two nights in St. Paul. Expect anthemic songs, lots of energy from Martin and special bracelets given to each concertgoer that will light up to the band's beats. Opening are Welsh popsters Marina & the Diamonds and Charli XCX. (7 p.m. Fri.-Sat., Xcel Energy Center, $47.50-$97.50, limited tickets available.) Jon Bream
A veteran of the Hotel Cafe Tours that have played the Fine Line, L.A. singer/songwriter Meiko mines breezy, lightweight indie pop on "The Bright Side," her just-released second album. It's a little sweeter than her debut, suggesting she yearns to be Colbie Caillat and no longer Ingrid Michaelson. Buddy opens. (9 p.m. Fri., 7th Street Entry, $10. Bream
After detouring into Judy Garland land and composing an opera, Rufus Wainwright returned to the more familiar terrain of baroque pop on this year's "Out of the Game," produced by Mark Ronson (Amy Winehouse, Duran Duran). Wainwright even gets danceable on the title track and "Jericho." There's also the pretty "Montauk," set sometime in the future when Wainwright's daughter Viva, who is 1, visits him and he prepares her for the concept of death. That tune also is about his mother, Kate McGarrigle, who died in 2010, as are many songs on the album. His concerts of late have included salutes to his mother and his dad, singer/songwriter Loudon Wainwright III. Adam Cohen, son of Leonard Cohen, opens. (7:30 p.m. Sat., Minnesota Zoo, $39.) Bream
Apart from its well received, sun-scorched showing at the River's Edge fest in June, Polia hasn't played a hometown gig since its sold-out album-release party at First Avenue on Valentine's Day. The electronics-addled, two-drummer rock band has been hard at work earning love around the country, playing everywhere from Jimmy Fallon's show to another big gig under the sun at Lollapalooza last weekend. Singer Channy Leaneagh (ex-Roma di Luna) has come into her own as a frontwoman, and she and the boys are throwing more new songs into their sets. Chicago techno-rap duo Supreme Cuts opens with local rockers Zoo Animal. (6:30 p.m. Sat., Cabooze Plaza, 18 & older. $25.) Chris Riemenschneider
Triathletes have nothing on Square Lake Festival goers, who tear through music, movies, biking, swimming and camping all in one day. The 10th annual artsy marathon is especially rich in the music department this year. Ambient twang-groove pickers the Pines will play under the stars. Acoustic blues veteran Spider John Koerner will play out in the midday heat (just as he did two weekends ago at the Newport Folk Fest). International Novelty Gamelan will play its own movie score. In between are indie-rock favorites Retribution Gospel Choir and Night Moves, which landed a deal with Domino Records after last year's fest. (2 p.m.-midnight Sat., 13359 Partridge Rd. N., Stillwater. $20 advance, $30 at gate, $5 by bike. SquareLakeFestival.com.) Riemenschneider
Boston ska-punk heroes the Mighty Mighty Bosstones enjoyed their commercial peak in 1997 with the hollerin' hit "The Impression That I Get" but then threw in the plaid towel in 2003. They came back a few years ago to tour sporadically and issued a well received album last year, "The Magic of Youth." Minneapolis is the finale on their seven-city "Summer Vacation" tour. Younger ska-core bands We Are the Union and Bomb the Music Industry open. (7 p.m. Sat., First Avenue. 18 & older. $25.) Riemenschneider
Veteran country/Americana singer-songwriter Rodney Crowell has been on a roll, with five consecutive stand-out albums since 2001 plus a 2011 memoir, "Chinaberry Sidewalks," about his dysfunctional childhood. This year's musical entry is "Kin," featuring songs co-written with poet/memoirist Mary Karr of "The Liar's Club" fame. While his previous four albums showcased mostly autobiographical tunes, "Kin" is more literary and more lyrical. The album is elevated by a series of simpatico guest vocalists including Lucinda Williams, Norah Jones, Vince Gill, Emmylou Harris and Rosanne Cash. (7 p.m. Mon., Dakota, $35.) Bream
