(Hawthorne Theatre, 1507 SE César E. Chávez) Take a preemptive Tylenol, because this show is going to end in you limping home covered in fun-bruises. Atlanta's Black Lips are back with a smoothed-out, less-distorted sound on new album Underneath the Rainbow, which feels like a natural (10-plus-years-as-a-band) progression that still maintains their signature grimy aura. The update comes as a relief; while 2007's Good Bad Not Evil was legitimately very great, and it's not Black Lips' fault they patented a reverbed-out, swampy scuzz-rock ripe for Xeroxing—I could do without the dudely rip-off bands that still pour out of basements and garages worldwide. Also from Atlanta (and on tour with the Lips) are raucous rock queens the Coathangers. They may be down to a trio (they're going forward without their keyboard player), but their new Suicide Squeeze full-length, Suck My Shirt, proves that the Coathangers' aggressive/melodic snarl/wink punk still does the trick.

(Secret Society, 116 NE Russell) Pretend Sweethearts are the duo formerly known as Vagabond and Tramp, made up of Brianna Lynn and Drew de Man. Their debut EP, I'm with You, is an easygoing, country-tinged trove of orchard-ripe tunes, guided by acoustic guitars and Lynn's striking, cloudless voice. It's a sweet and reassuring listen, covering a breadth of Americana styles without spreading itself too thin. Highlights include the meditative "Of the Sun" and the stripped-down, delicately gorgeous "Honey, Please Rain," which features Lynn and de Man harmonizing to remarkable effect. Tonight they perform an EP release show, joined by the Moonshine from Portland, and the Marshall McLean Band from Spokane. NED LANNAMANN

(White Owl Social Club, 1305 SE 8th) While the closing ceremony for the Sochi Olympics was a month ago, there's still one more gold medal to award—in the Portland Metal Winter Olympics. The single-elimination, battle-of-the-bands tournament has been ramping up to a conclusion since beginning in January, with the competition pitting two local metal bands against each other weekly. Tonight, the three final contenders vie for the gold. In one corner is the extra-nerdy prog-metal of Zirakzigil, whose Tolkien-referencing EP Battle of the Peak comes in a cassette packaged to look like a Super Nintendo cartridge. In another corner is the doom-metal of Disenchanter, whose EP On Through Portals is a time warp straight to the '70s. And in the third corner: Satyress, whose Dark Fortunes is a heavy, doomy nightride, captained by vocalist Jamie LaRose. May the best, evilest band win. MATTHEW W. SULLIVAN

(Foggy Notion, 3416 N Lombard) As the most obvious torchbearers for Portland's psychedelic revival, Cambrian Explosion possess both the youthful vitality and the chops to take you deep into a vortex of swirling soundscapes. The band's repetitive groove is given legs by deft keyboard mashing from the multi-talented Adria Ivanitsky, and triumphant wah-wah guitar from Nori Lockhart. The band's The Sun EP swims in trance-y seas, anchored by the explosive opener "Umbra of Mind." The soaring title track unfolds slowly, emitting hallucinatory drones and minimal vocals. In a relatively short time, Cambrian Explosion has commanded the attention of psych-rock purists as a pristine embodiment of the spirit of psychedelia's wanderlusting whims, and the attention is well deserved.
