POP/ROCK
Dave Barnes, the Nashville pop singer (how's that for an oxymoron?), is venturing into Jason Mraz/Jack Johnson territory on "White Flag," his new single that percolates with a reggae-suggesting bubbliness. The rest of the material on his new album, "Stories to Tell," released this week, is sunny-sounding pop that suggests he hasn't traveled far from either his Christian-pop roots or his desire to become the next John Mayer with a more upbeat demeanor. (7 p.m. Fri. Varsity, $18-$20.) Jon Bream
G. Love is back promoting his first album sans the Special Sauce, last year's "Fixin' to Die." Produced by brothers Scott and Seth Avett, it's kinda country, kinda bluesy (with covers of Son House and Bukka White) and kinda special. Scott Biram opens. (8 p.m. Fri. First Avenue, $24.50.) Bream
Nearly 20 years after its debut album, Mustard Plug is still skankin', and presumably there's still a market of ex-band geeks who dig out their checkered Vans and fedoras whenever the punchy sextet comes to town. Rocksteady Breakfast and Blue Waffle open. (10 p.m. Fri. Triple Rock, $10-$12..) Michael Rietmulder
Luke Zimmerman unavoidably gets compared to certain world-famous relatives of his (Uncle Bob and cousin Jakob Dylan), and he even falls a bit under the shadow of his older brother Seth of local 757s and Tangletown notoriety. On his new album, "Shoebox," though, he sounds more like the eighth (or ninth?) member of the Pines, offering poetic, rootsy ramblings with a dark-before-dawn vibe and picturesque acoustic guitar arrangements. (10 p.m. Fri., Amsterdam Bar & Hall. Free.) Chris Riemenschneider
For the 29th year, Boiled in Lead's annual St. Patrick's Day concert serves as one of the most authentic spots to celebrate the green holiday. You'll get a marathon set since the Twin Cities mainstays have the bill all to themselves. BiL recently released "The Well Below," a four-song EP. And fear not, booze hounds: The Cedar promises to keep plenty of Guinness on hand. (8 p.m. Sat. Cedar, $12-$15.) Jay Boller
Eccentric folk-punk duo Alexander Jackson Jihad has a lot to say. Guitarist/singer Sean Bonnette often delivers his sociopolitical commentary with quirky lines about Harry Potter, smoking meth and having oral sex with Satan. Touring with a full band for the first time, AJJ's live show should match the forcefulness of the sincere and restless anthems off last year's "Knife Man," the Phoenix duo's fourth studio album. With Laura Stevenson and the Cans, ROAR and Stop Drop. (10 p.m. Sat. Triple Rock, $10-$12.) Rietmulder
Woodstock propelled Melanie, then a 22-year-old underground folk singer from Queens, into candles-in-the-rain fame. After that post-Ravi Shankar downpour, she wrote "Lay Down (Candles in the Rain)," which landed her on the radio and pop charts, then followed with the chart-topping "Brand New Key" in 1971. At 65, Nashville-based Melanie Safka is still working it, a sincere, vibrato-voiced folk-pop singer who released "Ever Since You Never Heard of Me" in 2010. (7 p.m. Sun.-Mon. Dakota, $40.) Bream
After a four-year hiatus, Saul Williams returned to music with last year's "Volcanic Sunlight" -- an oddball pop record incorporating elements of trip-hop, forward-thinking R&B, philosophical lyrics and a TV on the Radio-meets-Bloc Party indie vibe. His musical absence hardly represented a creative lull, however: He starred in the film "Aujourd'hui," which premiered last month at the Berlin International Film Festival, and curated a poetry book due this fall. Hip-hopping techno-punk CX Kidtronik of Atari Teenage Riot fame opens. (9 p.m. Sun. Triple Rock, $15.) Rietmulder
