POP/ROCK Dave Longstreth's Brooklyn art-rock project Dirty Projectors travels in many directions. Its most recent CD, 2007's "Rise Above," reimagined 11 songs from Black Flag's seminal debut, and it contributed a quirky acoustic ditty ("Knotty Pine," featuring David Byrne) as the opening track of the Red Hot Organization's new Pitchfork-centric compilation, "Dark Was the Night." Longstreth promises to preview DP's upcoming album in this concert. (8 p.m. today, Walker Art Center, $15-$18.) (J.B.)
After starting in bluegrass with David Grisman, mandolin master Mike Marshall has traversed the musical spectrum -- from jazz to folk-chamber to classical. His current Big Trio features 2007 fiddling champion Alex Hargreaves and Wisconsin-bred bassist Paul Kowert. They will be joined by classical mandolinist Caterina Lichtenberg, lutist Mirko Schrader and Minnesota mandolin/violin virtuoso Peter Ostroushko. It sounds like a mandolin summit. (8 p.m. today, Cedar Cultural Center, $18-$20.) (J.B.)
It's easy to think of a solo Dan Auerbach gig as Black Keys Lite -- his solo debut "Keep It Hid" features a lot of the same howling vocals and gritty guitar parts heard on Keys discs, but none of the heavy pounding of bandmate Patrick Carney. A careful listen, however, will find a more personalized and Dylanesque songwriting style and some experimental sonic elements, along with a few surprisingly lovely acoustic numbers (especially "When the Night Comes"). Two promising openers: San Antonio's Hacienda, one of Auerbach's discoveries as a producer, plus all-girl Tennessee twang trio Those Darlins. (6:30 p.m. Sat., First Avenue. 18 & older. $14-$16.) (C.R.)
Texas' wild wall-of-roar quintet ...And You Will Know Us by the Trail of Dead was impressive enough to get signed by Interscope Records at the tail end of the '90s alt-rock boom, but it was never commercial enough to make a dent there. Dueling vocalists/drummers Jason Reece and Conrad Keely and their partners in noise come back to their indie roots storming, but don't forsake their ambitious, orchestral-punk sound (think: Fugazi + Sonic Youth) on the bold new disc "Century of Self." Good record, but it still doesn't match their frenzied, maniacal live shows. (9 p.m. Sat., Triple Rock. $15-$18.) (C.R.)
When Sweet Honey in the Rock comes to town, it doesn't just do a concert. The uplifting, enlightening female a cappella sextet does workshops and educational programs about music, domestic abuse and International Women's Day. The first event of this residency was Thursday, and Sweet Honey will be in town till Tuesday (see avaspecial.com for schedule). The big gig, of course, is a concert featuring its special blend of gospel, jazz, blues, reggae, hip-hop and African music. (8 p.m. Sat., O'Shaughnessy Auditorium, College of St. Catherine, 2004 Randolph Av., St. Paul, $20.50-$76.) (J.B.)
Cities 97 fave Dave Barnes is a sweet-voiced, garden-variety acoustic singer/songwriter. But the Nashville popster throws an unexpectedly wonderful curveball on his new EP, "You, the Night and Candlelight," with a deliciously soulful and often jazzy piano treatment of the Motown classic "My Girl." (7 p.m. Sun., Varsity, $13-$15.) (J.B.)
Minnesota-born, St. Louis-based singer/songwriter Erin Bode walks the line between folk and jazz. On her three albums, her sweet, subtle voice has been more convincing on covers of pop songs by Paul Simon, the Beatles and Simply Red than on original material, usually crafted with pianist/guitarist Adam Maness. (7 & 9:30 p.m. Sun.-Mon., Dakota Jazz Club. $20 & $15.) (J.B.)
Mishka was the first act signed to actor Matthew McConaughey's j.k. livin label, and he pretty well lives up to the ... hold it, hold it, exhale ... hype. Partly a sun-splashing reggae singer and partly a Dave Matthews/Jack Johnson-style strummer, the Bermuda-bred tunesmith is all about good vibes. Nothing wrong with that in this day and age. Dirty Heads open. (9 p.m. Mon., 7th Street Entry. 18 & older. $8-$10.) (C.R.)
