CANCELED: GROUPLOVE

7:30 p.m. • First Avenue • all ages • $20

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 touring behind last year's debut, "Never Trust a Happy Song," which convinced a lot of fans to not hate them just cuz they're happy and beautiful.CHRIS RIEMENSCHNEIDER

Zac Brown Band

7 p.m. • Target Center • $31.50-$69.50

Jason Mraz, Trombone Shorty and Amos Lee may have contributed to Zac Brown Band's new "Uncaged" album, but there's no question who is Brown's chief influence here: James Taylor. There are sweet vocals and a gentle and gentlemanly Southern-ness, complete with harmonies that evoke the group Alabama. However, get Brown and the boys onstage and they're likely to transform into a human jukebox that bursts into hits by Bob Marley, Aerosmith, Nirvana, Van Morrison or John Mayer. To be sure, in concert ZBB will also serve up its own country hits, including the Jimmy Buffett-soaked "Toes," the Alan Jackson-assisted "As She's Walking Away" and the ever-tasty "Chicken Fried." Levi Lowrey and Blackberry Smoke open. JON BREAM

THE GOURDS AND JAMES MCMURTRY

8 p.m. • Cedar Cultural Center • $20

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 displayed his novelist father Larry's knack for wry and vivid storytelling since his Mellencamp-produced 1989 debut album, and he has since grown into one mean guitar player. Now if only the Cedar could stock up on Shiner Bock for the show. J.B.

LAMB OF GOD

7 p.m. • Myth • all ages • $32

As of mid-summer, Lamb of God's 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 also includes In Flames, Hatebreed and British newcomers Sylosis.C.R.

ZAMMUTO

8 p.m. • McGuire Theater at Walker Art Center • $20

Months after announcing the breakup of his longtime musical partnership with Paul de Jong as experimental duo the Books in January, Nick Zammuto returned with an arty new album of his own. Despite a few cheekily bitter song titles, the eponymous LP 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. It's a little out there, but tangible song structures keep Zammuto's band-backed project in orbit. Eluvium opens. MICHAEL RIETMULDER

CASPA

9 p.m. • Studio B at Skyway Theatre, 711 Hennepin Av. S., Mpls. • 18-plus • $15-$20

An influential figure in dubstep's development, this U.K. DJ/composer teamed with London pal Rusko in 2007 to drop their iconic "FabricLive.37" mix, elevating the profile of the bass-driven genre. While Rusko has broken out commercially with glitzier productions, Caspa (who unfortunately refers to himself as "the dopest ghost in town") has continued on a grittier, less mainstream course. In other words, don't expect a similar Britney Spears collaboration from this wobble-lusting poltergeist. Caspa's U.S. tour coincides with the release of his recent "Dubstep Sessions 2012" mix. Smilodon, Durbin and KRL open. M.R.

DIERKS BENTLEY

8 p.m. • Treasure Island Casino • 18-plus • sold out

Before he hits the arena circuit next year with Miranda Lambert, Bentley is rocking a few smaller venues. That means his bluegrassy/folkie stuff from 2010's "Up on the Ridge" and this year's chart-topping ballad "Home" (co-written with Minneapolis' own Dan Wilson) will sound swell, as will all of Bentley's party songs like "Free and Easy."
