POP/ROCK While his other band has inched toward accessibility after pushing so many sonic boundaries, TV on the Radio guitarist, co-vocalist and beard-grower Kyp Malone has recorded a solo album under the name Rain Machine that's as wild as anything he's done. The songs range from tribal grooves to gritty neo-blues to freakish electronic, all tied together with starkly personal and spiritual lyrics. Should be fascinating live. Siren-voiced Brooklyn songwriter Sharon Van Etten opens. (9 p.m. today, 7th Street Entry. $15.) (C.R.)
On "The Truth According to Ruthie Foster," the truth is provided as much by Robben Ford's tasty guitar as by Foster's soulful vocalizing. Her previous CD, "The Phenomenal Ruthie Foster," was a more effective showcase for her voice, but "The Truth" still celebrates the considerable talents of this rootsy Texas troubadour. Opening are the delightful Davina and the Vagabonds, led by Minnesota's sly piano star. (8 p.m. today, O'Shaughnessy, $32.) (J.B.)
For their biggest Twin Cities show to date, Atlanta metal savants/saviors Mastodon have enlisted an opening act that threatens to steal some of their thunder, or at least take away some of the show's piousness: Dethklok, the government-baiting death-metal band that so brilliantly epitomizes and spoofs the genre on the hit Adult Swim cartoon "Metalocalypse." Onstage, the group is made up of the musicians who co-created the series, with their animated characters appearing onscreen behind them. High on Fire and Converge open. (7 p.m. today, Roy Wilkins Auditorium. $34.50-$37.) (C.R.)
After a 25-year run that was split up by frontman Ilia Lagutenko's service in the Red Navy (true story), Russia's biggest rock band Mumiy Troll is breaking into the United States with its first English-language EP, "Paradise Ahead," and its second tour to visit our familiar northern climate. American audiences have been filing them between Gogol Bordello and David Bowie. Murzik opens. (9 p.m. today, First Avenue. $12-$14.) (C.R.)
Known for colorful, love-or-hate-'em live shows, Ghostland Observatory is a psychedelic, hyper-grooving dance-rock duo with a ponytailed, howling, Freddy Mercury-copping singer and a cape-wearing beats maker. Their big coming-out was at their hometown's Austin City Limits Festival three years ago. They have since dazzled at Coachella and Lollapalooza but are only now making their Twin Cities debut. (9:30 p.m. Sat., Cabooze. $22-$25.) (C.R.)
Toronto singer Amy Millan is on a break from her full-time band, Stars -- not to mention her sometimes-group Broken Social Scene -- to promote her second solo effort, "Masters of the Burial," a downbeat but warm and serene collection that includes cover songs from Death Cab and Richard Hawley. Fellow Canadian band Bahamas opens. (9 p.m. Sat., Turf Club. $12.) (C.R.)
Celtic Woman may be an Irish group but the Dublin five have undertaken eight U.S. tours since their inception in 2004. Regarded as the vocal version of Riverdance, the slick vocal ensemble offers renditions of pop hits including Sting's "Field of Gold," Irish faves such as "Danny Boy" and the pandering original "O, America." (8 p.m. today, Mystic Lake Casino, $39-$49.) (J.B.)
Mute Math has too many piano parts and electronic beats for emo crowds and too highly polished/stylized vocals for indie-rock fans, but the New Orleans rock quartet is amassing a sizable fan base anyway. Its dark, brooding, romantic sound was a perfect fit for the "Twilight" soundtrack, and its backwards video for "Typical" was an MTV2 and online hit. The band is touring behind its second full-length disc, "Armistice." As Tall As Lions opens. (6:30 p.m. Sat., First Avenue. All ages. $20.) (C.R.)
