COUNTRY
There have been no bumps in the road for Keith Urban since he became a judge on "American Idol" last year. In fact, his "Fuse" album, released last fall, went to No. 1 on Billboard's country and pop charts and has yielded two country hits, notably a chart-topping duet with Miranda Lambert, "We Were Us." Always an exciting live performer, the guitar hero is touring with Little Big Town, the up-and-down coed quartet that reached a peak with the Grammy-winning "Pontoon" in fall 2012, and fresh-faced Dustin Lynch, who made some noise in 2012 with "Cowboys and Angels." (7 p.m. Sat., Target Center, $37-$82.) Jon Bream
BLUEGRASS
The masses may know Ralph Stanley from the Coen brothers' "O Brother, Where Art Thou" (he sang "O Death"), but the bluegrass patriarch has been almost as important to the genre as its king, Bill Monroe. With his brother Carter, he worked as the Stanley Brothers from 1946 until Carter's death in '66. A master of the clawhammer banjo, Stanley has carried on, mostly with the Clinch Mountain Boys, which features grandson Nathan on guitar and vocals. He turns 87 next month and is on a farewell tour that ends in December. Expect high lonesome vocals and plenty of pickin' and grinnin' from this joke-telling, old-school showman.(8 p.m. Fri., Cedar Cultural Center. Sold out.) Bream
POP/ROCK
New Jersey pickers Railroad Earth might not be the hippest or sexiest of the "newgrass" Americana string bands (see also: Trampled by Turtles), but it's one of the better ones to see live, with a little of Little Feat's Southern boogie adding to the fun. We're the second stop on a winter tour behind its seventh album, "Last of the Outlaws," which lands Tuesday. Missouri twang-rockers Ha Ha Tonka open. (8 p.m. Fri., First Avenue, $22.50-$25.) Chris Riemenschneider
Between last weekend's "Last Waltz" revival and next weekend's Janis Joplin celebration, the Cabooze hosts its longest-running January tribute show, Cash Only XIV, which actually started two years before Johnny Cash faded to black. The same core cast has been involved nearly every year, with Cash's friend Sherwin Linton — the Twin Cities' most storied country singer — as a centerpiece, plus tribute sets by honky-tonk stalwarts Trailer Trash and Dana Thompson, twangy rockers Ol' Yeller, the White Iron Band and Molly Maher and Erik Koskinen and at least one punky band, Eleganza. This one always goes well beyond "Ring of Fire" and "I Walk the Line." (8:30 p.m. Sat., Cabooze, $12-$15.) Riemenschneider
What do the Twin Cities hipsters in psychedelic rock band Buffalo Moon know about tropicália, bossa nova and other South American music genres? A lot, actually. Frontwoman Karen Freire is from Ecuador and led her bandmates on an extended stay below the equator in 2011, which partly explains the sonic DNA as well as the delayed ETA of their long-awaited third album, "Machista." Produced with Elliott Kozel of Sleeping in the Aviary notoriety, the record finally sees the light of day with a January release party that seems perfectly timed as a wild winter warm-up. With psyche-pop rocker Frankie Teardrop and a Tickle Torture DJ set. (11 p.m. Sat., Icehouse, $7.) Riemenschneider
Just because he's celebrating his birthday with a new 7-inch and a mainroom headlining gig doesn't mean Saturday night is all about Sean Anonymous. Proceeds from the bash and the two-track record benefit the Twin Cities Music Community Trust. Plus, the scrappy rapper is giving away copies of the booming release, featuring Lizzo and Phillip Morris, to the first 100 fans. He'll perform with DJ Name, Dreamcrusher and other guests. Toki Wright and Big Cats, Dem Atlas and Enemy Planes open. (8:30 p.m. Sat., First Avenue, $10-$12.) Michael Rietmulder
After earning a music degree at the prestigious University of North Texas, Calley Bliss tried her luck as a singer-songwriter in New York City, took a music-teaching job at an Idaho arts high school and recently returned to her native Twin Cities. Her 2010 disc, "Pigeonholed," showed a strong, dusky soul-jazz voice and an affinity for Anita Baker and minor-key piano ballads. Her new back-in-Minneapolis single, "The City," suggests deeper sophistication from the Patricia Barber school of moody, intelligent jazz. (11:30 p.m. Sat., Dakota, $5.) Bream
