POP/ROCK Chrissie Hynde didn't ask co-founding drummer Martin Chambers to play on the Pretenders' new country-tinged CD "Break Up the Concrete" -- she tapped drum legend Jim Keltner (CSNY, Traveling Wilburys, Dylan) instead -- but Chambers, who is one of rock's powerhouse rhythm keepers, will be on board tonight for "Precious," "Brass in Pocket" and other Hall of Fame hits as well as slabs of "Concrete." (9 p.m. today, First Avenue. Sold out.) (J.B.)
Argentinian TV-star-turned-pop-chanteuse Juana Molina fascinated as a one-woman band at the Cedar Cultural Center a couple of years ago, building her mesmerizing, polyglot sound with a bank of keyboards and other machines. Her fifth disc, "Un Dia," is another intriguing marriage of the organic and the electronic, and this time she's bringing a backing band. (8 p.m. today, Whole Coffeehouse, University of Minnesota, Coffman Union, Mpls., $5-$7.) (J.B.)
The New York Times' headline for the Jayhawks' album "Smile" -- "What if you made a classic and no one cared?" -- could be applied to Ben Weaver's "The Ax in the Oak," although local critics and the Current have given it its due. Issued last fall on Chicago's Bloodshot Records, it perfectly balances the St. Paul alt-folk troubadour's rustic, gravelly sound and Townes Van Zandt-ian bleak songwriting style with an elegant, Brian Deck-produced sonic backdrop and lyrics that pull the heartstrings just short of breaking. If you think Bon Iver has had some rough winters, you should hear Weaver. (9 p.m. today, Turf Club. 21 & older. $8.) (C.R.)
Here's what fans can expect from this weekend's two all-acoustic shows by Mark Olson and Gary Louris: a big chunk of their mellow new folk record ("Ready for the Flood"), nine or 10 early Jayhawks songs (yes, including "Blue") but no solo material or post-Olson Jayhawks tunes. These are the duo's first concerts together since 1995 in the city that bred them, so you can probably also expect a little sentimentality. Read an interview with Olson and Louris at startribune.com/music. (8 p.m. Sat., 5:30 p.m. Sun., Varsity Theater. Sold out.) (C.R.)
Now in its fourth year and one of the hippest parties in town, the Bands for Band benefit helps keep music instruction alive at three Minneapolis schools, Sullivan, Sanford and Seward. (2:30 p.m. Sat., Minneapolis Eagles Club. $5-$10; $25 families.) (T.S.)
Flogging Molly is out on its fifth annual Green 17 Tour, which is its way of milking St. Patty's Day into one monthlong bash. The Los Angeles-based Celtic punk band -- the favorite Irish band for MySpace cadets -- puts on better live shows than it does records, although last year's collection, "Float," had some terrifically feisty, Pogues-copping tracks such as "Requiem for a Dying Song" and "Punch Drunk Grinning Soul." (8 p.m. Mon., Myth. All ages. $23-$25.) (C.R.)
Although he may cringe at the comparisons, West Coast singer/songwriter Brett Dennen's sensitive, acoustic-guitar pop comes from the same school as Jason Mraz, John Mayer and Jack Johnson. Dennen's breakthrough hope on his third CD, "Hope for the Hopeless," is the lightly soulful single "Make You Crazy," featuring Femi Kuti. (8 p.m. Mon. Varsity Theater. Sold out.) (J.B.)
Once typecast as an emo band, the Appleseed Cast has evolved into a shimmering, instrumental-leaning outfit with atmospheric "post-rock" songs evocative of mellower Yo La Tengo, Explosions in the Sky, Sigur Ros and other starlight-gazing bands. The Lawrence, Kan.-based group's sixth album, "Sagarmatha" (what the locals call Mount Everest), just came out Tuesday on the Militia Group. Local labelmates One for the Team open. (5 p.m. Tue., Triple Rock. All ages. $11.) (C.R.)
