SUMMIT BACKYARD BASH
For one of the most prominent acts in town, Doomtree sure hasn't performed here much of late -- only once since last winter's Blowout gigs. The hip-hop collective finally returns to headline the Summit Brewery's Backyard Bash, a parking-lot beer fest also featuring breakout indie-pop trio Now, Now, ambient rockers Halloween, Alaska, the eclectic folk-rock of Caroline Smith & the Good Night Sleeps and ex-Alarmist singer Eric Lovold's new band, the Heartbeats.CHRIS RIEMENSCHNEIDER
WHY?
Oversharing and erratic, the monotone musings of Why? rapper/singer Yoni Wolf hit on a scattershot range of tones (humorous, morbid, societal), but he's consistently sharp with a pen. The frontman -- who's also co-founder of esteemed L.A. avant-indie label Anticon (Baths, Dosh, Tobacco) -- has been the driving force behind the hip-hop/indie-rock/folk hybrid since 1997. Why?'s fifth full-length, next month's "Mumps, Etc," was partially inspired by Wolf's recent bout with the rare disease. Doseone, Serengeti and Jel open.JAY BOLLER
BLACK 5 YEAR ANNIVERSARY
10 p.m. • First Avenue Record Room • 18-plus • $7
Black has been the only consistent night for serious techno enthusiasts to get their fix for five years running. It's celebrating its fifth anniversary with a special lineup hand-picked by resident DJ/producer Aaron Litschke, and it's a stellar one: it features Chicago-based DJ/producers Submerge and Ricardo Garduno -- two of the most respected techno players in the game -- and Komprezzor, who's known for his dense, hypnotic rhythms culled from classic drum machines. Saturday's show kicks off a month of weekly Black anniversary events. JAHNA PELOQUIN
