POP/ROCK This is the time of year when things usually wind down for him, but Mason Jennings' annual return to First Avenue finds the singer/songwriter gearing up for two self-released albums. One is a recording of last year's homecoming show: "Live at First Ave" captures the finale to his "electric" tour behind 2009's studio record "Blood of Man." The other new collection, "The Flood," features 15 "lost" songs that Jennings re-recorded from demo tapes, some of them rediscovered when his father cleaned out his basement. Dad deserves a producer credit for that one, especially after the disc debuted at No. 1 on iTunes' singer/songwriter chart last week. Jennings will have his band with him for both shows. Juno Award-winning Canadian folkie Sarah Harmer is a great fit to open. (7 p.m. Sat.-Sun., First Avenue. 18 & older. $22-$25.) (C.R.)
While several of its noisemaking peers from the early-'90s Twin Cities scene reunited this summer for Amphetamine Reptile's 25th anniversary bash, Arcwelder had gone out to Chicago several years earlier to play the silver birthday for Touch & Go Records, which issued four of its albums, filing them alongside the likes of Shellac and the Jesus Lizard. The craftily powerful power trio still offers a hometown show or two per year, just enough to be missed. (10 p.m. Sat., 7th Street Entry. $6.) (C.R.)
The newly invigorated Wild Tymes, now booked by former First Avenue manager Steve McClellan, has an interesting four-band bill Saturday. The Chinch Bugs -- three females and "The Sexman" on drums -- start the night off with witty, tuneful, gently subversive pop, complete with occasional oboe. Then come the rollicking Monica & the Molecules with the Caveman on keys and Fancy Ray McCloney as guest emcee. The Molecules are playing their final show before a one-year hiatus. Pop-punk pleasers Superman Curl are next, with the Rank Strangers closing the show. (8 p.m. Sat., Wild Tymes, 33 W. 7th Pl., St. Paul. No cover.) (T.S.)
For its annual Jingle Ball at Target Center, KDWB has lined up a parade of hot hitmakers, none of whom is a legit arena attraction. Chart-toppers B.o.B. ("Nothin' on You," "Airplanes") and Taio Cruz ("Break Your Heart," "Dynamite") return from KD's Star Party in May. Also on board are Latin heartthrob Enrique Iglesias, piano popster Sara Bareilles ("Love Song," "King of Anything"), Disney star Selena Gomez, one-hit wonder Mike ("Cool Than Me") Posner, Ke$ha collaborators 3OH!3 and the Ready Set, a one-man band discovered by Pete Wentz. (6:30 p.m. Mon., Target Center. Advance tickets sold out but listen to 101.3 FM for giveaways.) (J.B.)
About time. Since Broken Bells' one and only record came out nine months ago and didn't maintain its initial buzz, folks might need a primer on who's even in the band: It's the "Strawberry Fields"-flavored side project of Shins singer James Mercer and production wiz Brian Burton, aka Danger Mouse of Gnarls Barkley fame. Their kaleidoscopic pop flowed beautifully under the stars during South by Southwest but dried up in broad daylight at the Austin City Limits Festival. An up-close wintery gig inside First Ave will likely fall somewhere in between. They've been rounding out their set lists with a couple of way-cool cover songs. Quirky Chicago openers Maps & Atlases issued an impressive debut on Barsuk Records in June. (8:30 p.m. Mon., First Avenue. 18 & older. $29.50.) (C.R.)
Last seen opening for Grammy-winning banjo man Steve Martin at the Orpheum, the all-star avant-bluegrass Punch Brothers dazzle on disc and wow in concert. It's not just the fast picking, high-lonesome vocals and imaginative repertoire (covers of Radiohead, the Strokes and the White Stripes), but it's the too-hip-for-the-room humor. Frontman Chris Thile is a first-class cut-up as well as a mandolin virtuoso. (8 p.m. Wed., Fine Line, $21.50-$25.) (J.B.)
Now that iTunes is Beatles-approved and the group has its own "Rock Star" video game, Curtiss A's John Lennon Tribute will have to be better tailored to all the younger fans who might start showing up alongside the old faithfuls -- you know, the regulars who wouldn't even let a wicked snowstorm keep them away a few years ago. For starters, kids' attentions span could never withstand the three-hours-plus of tunes, so let's lose all the cool nuggets rarely heard in other Fab Four tribute events like "Baby You're a Rich Man" and "Happiness Is a Warm Gun." Maybe ditch "Give Me Some Truth," "John Sinclair" and other songs with pre-Obama political references, too. And what's with Curt's oversized backing band sounding so rehearsed and on top of the material? Not cool, dudes. A couple of younger bands, Communist Daughter and Total Babe, will perform during Curt's break to promote the excellent new charity CD, "Minnesota Beatle Project, Vol. 2." This year's 31st annual show falls on the 30th anniversary of Lennon's slaying. (7:30 p.m. Wed., First Avenue. 18 & older. $13.) (C.R.)
While their former labelmates Green Day have their name in lights on Broadway, the Queers are happy to still be playing clubs that at least put their name on a website. Not that Joe Queer and his ever-smarmy and raunchy, Atlanta-based pop/punk trio ever really had a chance of going mainstream, a point reiterated on their first album in three years, "Back to the Basement," which includes such titles as "I Knew GG When He was a Wimp" and several unprintable ones. It also features a cover of Black Flag's "White Minority." (9 p.m. Thu., Triple Rock. 18 & older. $10-$12.) (C.R.)
