Devendra Banhart: Every year or so, Walker Art Center sets loose a polymath on an ambitious, multi-night series of eclectic collaborations. This time it's the acid-folk singer-songwriter (and visual artist) Banhart. On Friday he'll open solo and then match up with Lucky Dragons, Jessica Pratt, Helado Negro and William Basinski. Saturday will begin with Banhart's regular touring band then shift into the collaborative gifts of Rodrigo Amarante, Hecuba and Harold Budd. Co-presented with the SPCO's Liquid Music series, the whole shebang is entitled "Wind Grove Mind Alone." Expect daring experiments. (8 p.m. Fri.-Sat., Walker, $24-$28.) Britt Robson

Kenny Rogers: "The Gambler" hitmaker knows when to fold 'em. After a career that started in the 1950s, the "Just Dropped In (To See What Condition My Condition Was In)" rocker turned country superstar is in the midst of his farewell tour. Rogers was so hot in the 1980s that "Lady" and "Islands in the Stream," his duet with Dolly Parton, reached No. 1 on both the country and pop charts. Expect to hear those hits, "Reuben James," "Coward of the County" and "Lucille" one last time on what's billed as Rogers' Final World Tour: The Gambler's Last Deal. Opening is Linda Davis, Reba McEntire's duet partner on "Does He Love You" and the mother of Lady Antebellum's Hillary Scott.

The Lowland Lakers: This Duluth-rooted, Minneapolis based country/folk trio is celebrating a big charmer of a debut album, "The Mississippi Is Between Us Now," led by soulful singer in Haley Rydell and full of rich three-part harmonies. (10:30 p.m. Fri., Dakota, $7.) Riemenschneider

Many newer metal stars are also on the schedule, including Shinedown, A Day to Remember, Ghost, Asking Alexandria, Bring Me the Horizon and Nikki Sixx's Sixx A.M.

Birds of Chicago: Wife-and-husband team Allison Russell and JT Nero cut their teeth in separate bands (Po' Girl and JT & the Clouds, respectively) but have truly found harmony together in their jazzified soul/pop group. Roots music wiz Joe Henry just produced their second album, "Real Midnight," full of candlelit ballads and jangly, lovelorn ditties led by Russell's goosebumps-inducing voice. Ben Lubeck of Farewell Milwaukee opens. (7:30 p.m. Thu., Cedar Cultural Center, all ages, $15, Riemenschneider

Four Tet: London electronic instrumentalist Kieran Hebden earned the "folktronica" tag with his early-'00s albums for Domino but has since been all over the map and collaborated with the likes of Thom Yorke and Laurie Anderson.
