Derek Sheen, Marcus Coleman, Kayla Ruth
Comedian Derek Sheen knows how to put a funny new spin on Portland's eccentricities. He's self-deprecating, charming, and a hot mess of whimsy and nerdiness, who cracks himself up nearly as much as everyone else. He's pretty much the spiritual little brother to Patton Oswalt. (Fri 8 pm, The Secret Society, $10) COURTNEY FERGUSON

Slang, Hutch Harris, WL
The newly-minted garage rock supergroup headed up by Quasi/Sleater Kinney drummer Janet Weiss, former Thermals bassist Kathy Foster, Viva Voce guitarist Anita Lee Elliott, and Modern Kin vocalist Drew Grow make their way to St. Johns for a hometown show at the Fixin' To.

Mos Generator, Holy Grove, Pushy, Hippie Death Cult
Holy Grove takes all the evil things from classic metal, doom, and blues and transforms them into a hulking beast—and that's just the rhythm section. Vocalist Andrea Vidal sings with power and precision, and guitarist Trent Jacobs unleashes riffs that are sludgy yet dexterous. (Sat 8:30 pm, High Water Mark, $7-10) MARK LORE

Saroon, Sheers, Kelli Schaefer
Saroon's music unfolds unhurriedly, using arpeggiated chords, dreamy studio effects, soft horn parts, honeyed backing vocals, and elongated melodies to build a comforting sound world. Imagine the Long Winters’ John Roderick fronting a drowsy baroque-pop band, and you’re in the right ballpark. (Sat 8 pm, Turn! Turn! Turn!, $7) BEN SALMON

DJ Action Slacks' annual Halloween dance party returns to the Kenton Club with the all the classic soul, Motown, R&B and blues grooves from both her collection and DJ Wildman James' that you can fit in your pillowcase for the night. (Sat 9 pm, Kenton Club, $7-10)

Gaytheist, Sweet Reaper, Milk Bath, Bothers
If the music of Gaytheist were a vehicle, it would be a semi, late on its delivery, blazing down I-5, the speed limit only a laughable suggestion as the trucker begins to have Tron-like hallucinations from 38 hours of no sleep and caffeine-pill cocktails. With only three members, Gaytheist leaves you wondering how they create such a heavy, intricate layering of sound. (Sun 8 pm, High Water Mark, $8) CAMERON CROWELL

Blesst Chest, Wet Fruit, Inhalant
Portland prog-rock outfit Blesst Chest head up the latest installment of Sunday Sessions at Rontoms in support of their new XRay Records-issued album, Casual Corner. (Sun 8 pm, Rontoms, free)
