(Cleveland High School, 3400 SE 26th) It's time to go back to school, but this time class will be taught by two of Portland's biggest and best bands. The Helio Sequence and Talkdemonic play a high school gig tonight, with student band Yeti Sweater opening. It's a benefit for Music in the Schools, to raise money for music education in Portland high schools. Get ready to rock out, just remember no running in the halls. NED LANNAMANN

(Aladdin Theater, 3017 SE Milwaukie) Mark Kozelek is well known for treating his audience like absolute shit. But the abuse is definitely worth tolerating—for the uninitiated, Kozelek is the brains behind Red House Painters and Sun Kil Moon, two musically different but evenly brilliant vehicles for Kozelek's gorgeous pop dirges. Two tracks off the Red House Painters' eponymous second (which fans have rechristened Rollercoaster)—"Grace Cathedral Park" and "Katy Song"—are among the seven songs that have ever actually brought me to tears. Kozelek's arrogant, sure—but I'll argue arrogance is permissible if you're actually brilliant. MORGAN TROPER

(Doug Fir, 830 E Burnside) Bay Area trio Om have morphed from theosophical doom-metal minimalists to theosophical psych-drone minimalists boosted by an uncorny Eastern mysticism. They're so heavy they're featherlight. Ain't nobody like 'em. Master guitarist Sir Richard Bishop is a national treasure whose sound is international. He's revivified ye olde American baroque-folk convolutions of John Fahey and his acolytes, but his 10 dexterous, articulate digits speak fluently in Arabic, Central European, North African, spaghetti Western, raga, drone, and other modes, too. Experiencing the fluidity, beauty, and inventiveness of Bishop's playing is spiritually revelatory. DAVE SEGAL

(Jackpot Records, 3574 SE Hawthorne) I hate the term "girl crush" because who gives a shit if, as a woman, your crush is a girl or a boy? That said, I have a total no-pronoun-necessary crush on multi-instrumentalist Thao Nguyen of Thao and the Get Down Stay Down. She is, at once, folk, punk, feminine, and badass. She has collaborated with Mirah and the Portland Cello Project, and she totally nailed a cover of "Push It" with Fred Armisen and Carrie Brownstein as her backup band. Be my best friend, okay, Thao? We can make cupcakes and listen to records and it'll be like an episode of Girls, but without the insufferable conversation and constant bad decisions. MEGAN SELING

(Holocene, 1001 SE Morrison) Like all musical rages, the disco-pop trend has had varying results, many of which have been annoying. As Onuinu, Dorian Duvall is at the top of the genre—and it seems likely to last. For one thing, you get the feeling that he's in it for reasons other than sexy clothes and the fun of copying beats from much-loved songs that are four decades old. Duvall is a craftsman, and the breadth of his knowledge deepens his dance confections so that they become truly interesting rather than merely enjoyable. His first full-length, Mirror Gazer, is definitely a dance album, but its bouncy beats and addictive melodies are awash in synth effects that range from dreamy and new age to something along the lines of Toro y Moi. The album's standout, "Always Awkward," epitomizes everything that's best about Onuinu: the sexiness of Duvall's voice, rock-solid songwriting, and detail-oriented production. RW
