Probably the last time Yanni played a small theater in the Twin Cities was with Chameleon, his Minneapolis rock band before he became the maestro of romance. Yes, Yanni was one of us, a University of Minnesota grad and a rockin' keyboardist. Now he is a global icon who's headed to South America and China after a North American tour, promoting "Live at El Morro, Puerto Rico." His group still includes percussionist Charlie Adams, drummer in Chameleon. (8 p.m. Fri., Mystic Lake Casino, $57-$68.) Jon Bream
After last year's welcome return of his better-known trio Low, Alan Sparhawk's continued commitment to Retribution Gospel Choir might have seemed in question. Not anymore. The Duluth trio has stormed back with "The Revolution EP," anchored by the power-crunch anthem "The Stone" and three more heavy hitters. RGC is stopping here on its way home from a seven-city tour. The Farewell Circuit opens. (9 p.m. Fri., Triple Rock. $12.) Chris Riemenschneider
Since picking up its Minneapolis roots and relocating to Portland, Ore., in 2009 -- before IFC's "Portlandia" series made it uncool to do so -- folky boy/girl harmony group the Lower 48 has developed a plusher sound and a pretty decent following all over the country. Its second album, "Where All Maps End," offers charming traces of Sufjan Stevens and local favorites Communist Daughter while spotlighting the sweet chemistry between singer/songwriters Ben Braden and Sarah Parson. Eau Claire's Sky Lion opens. (8 p.m. Fri., Cedar Cultural Center. All ages. $10-$12.) Riemenschneider
Six months after packing the Entry, and about 200 spins later for his single "Polish Girl" on 89.3 the Current, Alan Palomo's one-man synth-pop band Neon Indian returns to play the First Ave main room. The Texas-bred chillwave wiz kid's sophomore album, "Era Extraña," extracts heavily from the era of big hair and bad Spandau Ballet videos, but it does offer mesmerizing moments of mopey bliss. The record was mixed by Dave Fridmann, whose pals the Flaming Lips collaborated with Palomo on an EP last year. San Francisco dance trio Lemonade opens. (9 p.m. Fri., First Avenue. $14.) Riemenschneider
Tortoise makes a point of disavowing labels, jumping from jazz to dub to krautrock and so on with brainy ease. The instrumental rockers will be joined by the Minneapolis Jazz All-Stars --Douglas Ewart, Mike Lewis, Greg Lewis, JT Bates and Michelle Kinney. (8 p.m. Fri., Walker Art Center, $18-$22.) Jay Boller
The delightfully twisted Loudon Wainwright III contemplates family and mortality on his splendid new "Older Than My Old Man Now." He's frank and funny as he addresses aging, health ("My Meds"), a longer life, divorce and outliving his journalist father ("The Here & the Now," featuring his four children and the mother of one of them). Laugh until you die. (8 p.m. Sat., Cedar Cultural Center, $25-$30.) Bream
Folky California songstress Kina Grannis, 26, won the Doritos Crash the Super Bowl Contest in 2008, but instead of becoming a cheesy pop star she carved out an impressive niche as a wholesome indie act, highlighted by heavy VH1 rotation for her jellybean-starring video "In Your Arms." Her latest album, "The Living Room Sessions," is an all-covers set featuring songs by Bon Iver, Kings of Leon and Katy Perry. (6:30 p.m. Sat., Varsity Theater. All ages. $15-$17.) Riemenschneider
