POP/ROCK Grouplove owes much of its success to such millennial-seeking marketing avenues as an iPod commercial and video-game placement, but the gleeful Los Angeles pop/rock band also goes over well on that oldest of outlets -- the stage. Hippie-hunk frontman Christian Zucconi, cutie-pie keyboardist Hannah Hooper and the rest of their smiley crew are wrapping up their tour behind last year's debut, "Never Trust a Happy Song," which convinced a lot of fans to not hate them just 'cause they're happy and beautiful. (7:30 p.m. Sat., First Avenue. All ages. $20.) Chris Riemenschneider
Two mainstays of the Austin, Texas, music scene, the Gourds and James McMurtry come from different corners of the Americana/country-rock realm. The rowdier, Cajun-ized Gourds are touring behind their spirited 10th album, "Old Mad Joy," produced by former Dylan and Levon Helm guitar ace Larry Campbell. McMurtry has his novelist father Larry's knack for wry and vivid storytelling and he's grown into one mean guitar player. Now if only the Cedar could stock up on Shiner Bock for the show. (8 p.m. Sat., Cedar Cultural Center. $20.) Riemenschneider
Months after the breakup of his experimental duo the Books, Nick Zammuto returned with an arty album of his own. Despite a few cheekily bitter song titles, "Zammuto" doesn't feel like a perfunctory rebound record. The tantalizing prog-pop effort finds an electronic/organic equilibrium, with skittering synth sounds and vocal effects brushing up against guitars and au natural percussion. Ambient-classical act Eluvium opens. (8 p.m. Sat., Walker Art Center, $20.) Michael Rietmulder
An influential figure in dubstep's development, U.K. DJ/composer Caspa has continued on a grittier, less mainstream course while former partner Rusko has broken out commercially. In other words, don't expect a Britney Spears collaboration from "the dopest ghost in town." (9 p.m. Sat., Studio B at Skyway Theatre, 711 Hennepin Av. S., Mpls. $15-$20. 18-plus.) Rietmulder
As of midsummer, Lamb of God frontman Randy Blythe was stuck in a Prague prison on charges he caused the death of a fan pushed off a stage, but lo and behold his Virginia-bred death-metal band is back for its second Twin Cities area concert in three months. The strong lineup includes In Flames, Hatebreed and British newcomers Sylosis. (7 p.m. Sun., Myth. All ages. $32.) Riemenschneider
A regular visitor to the Dakota since 2004, rebounding R&B star Bettye LaVette is riding high thanks to her raw and riveting new memoir, "A Woman Like Me," and an impressive new album, "Thankful N' Thoughtful," with songs by Bob Dylan, Neil Young and Sly Stone plus a penetrating reading of Gnarls Barkley's "Crazy." See an interview with LaVette in Sunday's Variety section. (7 p.m. Mon.-Tue. Dakota, $45.) Jon Bream
Since their legendary 1999 collection "69 Love Songs," the Magnetic Fields have made quick, quirky and clever odes to amore their signature trademark. Songwriter Stephin Merritt delivered some delightfully odd ones on the band's latest, "Love at the Bottom of the Sea," a lighter and poppier collection that landed something of a surprise hit in "Andrew in Drag." Opener Gal Musette is a ukulele-plucking 14-year-old California girl who's penning 70 love songs in response to Magnetic Fields. Oh, fer cute! (8 p.m. Tue., First Avenue. $30.) Riemenschneider
Given its Brooklyn soul pedigree, it would be easy to file the Menahan Street Band in the heard-it-before bin. But this mishmash of members from the Dap-Kings, Antibalas and Budos Band is clearly its own beast. More contemporary than the Dap-Kings and sultrier than the other roots projects, this instrumental soul-funk quintet is suited for a velvet-draped after-hours lounge. (10:30 p.m. Tue., 7th Street Entry, $15. 18-plus.) Rietmulder
