At 88, blues giant B.B. King in concert is more about laughs than Lucille, his trusty guitar. He tells some stories and jokes, lets his band carry the load and, a few times each night, will rise to the occasion to deliver with authority a classic such as "The Thrill Is Gone," which is as true as it is ironic. Opening is Sena Ehrhardt, the fast-climbing blues darling from Rochester. (8 p.m. Fri., Mystic Lake Casino, $59-$69.) Bream

He's well-known as the musical mayor of St. Paul and one of the Twin Cities' most poetic Americana songwriters, but Martin Devaney covers a lot of other ground on his sixth album, "House of Rust." It opens with a song about an eatery in Austin, Texas, and visits the South Dakota prairie before winding up at St. Paul's Fountain Cave, with several stops at Heartbreak Hotel along the way. Recorded on the Iron Range at Rich Mattson's Sparta Studio, the music ranges from rollicking, Slim Dunlap-style rave-ups to moody and dark, Joe Henry-ian downers, with backers including fiddler Jake Hyer, Bellwether drummer Mick Wirtz and Big Wu keyboardist Al Oikari. Mattson's Ol' Yeller opens the release party with the Cactus Blossoms. (8 p.m. Fri., Cedar Cultural Center, $10-$12.) Chris Riemenschneider
Ra Ra Riot is touring without its co-founding cellist, Alexandra Lawn, which may or may not have something to do with the fact that the collegiate rockers from Syracuse, N.Y., are also touring with a more synth-poppy, less chamber-folky sound à la their new record, "Beta Line." The disc tellingly opens with a giddy foot-tapper called "Dance With Me" and maintains a light, bouncy vibe throughout. Southern California beach boys Cayucas open. (9 p.m. Fri., First Avenue, $15.)

After two well-crafted pop albums that made her a Twin Cities radio favorite, Scottish-born, London-based singer/songwriter KT Tunstall has gone all artiste on her third album, "Invisible Empire/Crescent Moon." As dry as the desert depicted on the cover photo, this is a slow, stripped-down, deeply felt collection about divorce and death. The disc has some lyrical images, ambient textures and glacial vocals that suggest Beth Orton and k.d. lang. Tunstall may not have lang's shimmering power, but she does have her glass-of-wine-alone intimacy. (8 p.m. Sat., Cedar, sold out.) Jon Bream
Other-worldly sci-fi metal gurus GWAR still sound like they're having a bloody good time on their new album, "Battle Maximus," even though the title and themes pay homage to late guitarist Cory "Flattus Maximus" Smoot, who died of a heart attack after the band's bus pulled away from First Avenue in November 2011. Ringleader Oderus Urungus and his mavens have produced an all-new stage show for their Madness at the Core of Time Tour, featuring Metal Blade labelmates Whitechapel with Iron Reagan and another costumed fantasy band, Band of Orcs. (6 p.m. Sat., First Avenue, $20-$23.) Riemenschneider
Eight years after Gary Louris produced their breakthrough album "Exploration," married picking partners Sarah Lee Guthrie and Johnny Irion got another Golden Smog alum, Jeff Tweedy, to co-curate their latest with his Wilco bandmate Pat Sansone. The duo play around with their sound on "Wassaic Way," adding a Beatlesque psychedelic pop sheen without forsaking their sweet harmonies and the Guthrie family folk tradition. (9 p.m. Sun., 7th Street Entry, $12.) Riemenschneider
Singing surfer dude Jack Johnson is totally chill on last month's "From Here to Now to You," his sixth studio album. He offers more breezy, hummable ditties with sweet, simplistic messages like "I Got You" and "Never Fade" ("our love can never fade"). Occasionally, he shows a willingness to pick up the tempo. "Tape Deck," a flashback about his days in a punk band, swings gently. The blithely syncopated "Shot Reverse Shot" could be a mellow Billy Joel on acoustic guitar. And "Radiate" gives off a jaunty reggae-funk vibe. (7:30 p.m. Mon., State Theatre, sold out.) Bream
As with the BoDeans, we have to accept Barenaked Ladies with one of their lead singers no longer participating. This summer's "Grinning Streak" is BNL's second studio album without Steven Page. Despite the title, this is a mostly serious, reflective pop album with an electronica sheen, though frontman Ed Robertson gets a little playful on "Boomerang" and "Odds Are." Whitehorse opens. (7:30 p.m. Wed., State Theatre, $37.50-$65.) Bream
