One of several U.K. buzz bands making its stateside landing at South by Southwest two weeks ago, Welsh trio the Joy Formidable genuinely burst onto the scene at the festival. Frontwoman Ritzy Bryan looks like a china doll but plays like a pit bull, and her band's debut for Atlantic Records, "The Big Roar," boasts shoegazing fuzz-pop gems laden with Breeders-like hooks. Opening quartet Mona is blowing up early in England, much like fellow Tennesseans Kings of Leon did. The Lonely Forest also performs. (9 p.m. Wed., 7th Street Entry. 18 & older. $12.) Chris RiemenschneiderIf anyone can transform cavernous Roy Wilkins Auditorium into a Euro club, it's the internationally renowned Dutch DJ Tiësto. He creates throbbing trances of the highest order -- music that sounds like a hit of Ecstasy feels. Tijs Verwest, the man behind the Tiësto moniker, has also moonlighted as a producer and recording artist since his emergence in 1996. His latest LP, 2009's "Kaleidoscope," features collaborations with Jonsi, Emily Haines and Nelly Furtado. This gig is part of the 175-date-plus "Kaleidoscope World Tour." (8 p.m. Fri., Roy Wilkins Auditorium, $62-$72.) Jay Boller
DeVotchKa seems to have swallowed the cineplex Kool-Aid. Since doing scores for "Little Miss Sunshine" and "I Love You Phillip Morris," the Denver ensemble has come across as less alt-gypsy and more cinematic. The new album "100 Lovers" features a moody melting pot of Eastern European, mariachi, Bollywood and Hollywood that is overall more mushy than compelling. (9 p.m. Fri., First Avenue, $25.) Jon Bream
The Birthday Suits have torn up Twin Cities clubs over the past half-decade without their Japanese heritage ever really being an issue, until now. The wall-bouncing, ear-shattering punk duo is heading up a local benefit for Japan's relief efforts with some of their best noisemaking pals, including current pop/punk darlings Pink Mink and the Gateway District, featuring members of the Soviettes, Rivethead and Banner Pilot. Still Pacific opens. (10 p.m. Fri., Triple Rock. 18 & older. $10.) Riemenschneider
If you're partial to roots-rock Americana songwriting, the double bill of James McMurtry and the Bottle Rockets should be plenty enticing. Austin, Texas troubadour McMurtry gained a legion of new fans five years ago when his biting portrait of working-class America, "We Can't Make It Here Anymore," became a YouTube sensation. And the perennially underrated and overachieving Bottle Rockets, the pride of Festus, Mo., have an ace songwriter themselves in Brian Henneman. (9 p.m. Fri., 400 Bar. $16.) Tom Surowicz
Buried far underneath the intoxicating roar of his guitar, J Mascis has written some damn lovely, melodically golden songs as the frontman of Dinosaur Jr. His latest Sub Pop-issued solo album, "Several Shades of Why," strips away all the noise with surprisingly sophisticated results. Philadelphia mad man Kurt Vile, who played backup on Mascis' record, is a must-see opener with his band the Violators and their buzzing second album for Matador Records. Fauna opens. (9 p.m. Sat., 7th Street Entry. Sold out.) Riemenschneider
An early frontman for Southern Cali's most celebrated punk band (Black Flag) before spending a decade with one of its most underrated (the Circle Jerks), Keith Morris might have actually just joined his best group yet. No kidding. It's called OFF! and it features other Los Angeles vets from Rocket From the Crypt, Redd Kross and Burning Brides. Their sound is at once epic and cocky like Led Zeppelin but raw and dastardly like the wild horses Morris rode in on. Steve Albini-produced Sacramento hardcore band Trash Talk opens with Much Worse. (9 p.m. Sun., Triple Rock, $13-$15. 18 & older.) Riemenschneider
Iris DeMent is one of those much-revered underachievers. Or at least she operates under the radar (and doesn't update her website). She's beloved for her high lonesome voice and her ability to wed the sensibilities of the Carter Family with the poignant songwriting of a John Prine. She released three impressive albums in the 1990s and only one since then, 2004's "Lifeline," a collection of old-time church and gospel tunes. (7 p.m. Sun., Dakota, $45.) Bream
