At Nordstrom Hall’s Optical 1: Sine Your Name Across My Heart showcase, Rafael Anton Irisarri and the visual artist Lissom joined ex-Slowdive drummer Simon Scott for a glacially evolving set of exquisite beauty. Scott and Irisarri used laptops to manipulate field recordings from Twin Peaks and other outposts of Pacific Northwest nature—birdsong, mysterious, quiet scrabblings, rushing water, and ominous bass rumbles—while Lissom flashed calming vistas of said nature spots on the big screen behind the musicians. Scott occasionally generated crystalline tones with his guitar and Raf sometimes bowed his to create cello-like timbres. At one point, a gray drone materialized, buttressing elegiac guitar chimes that evoked a dewy placidity. The last 15 minutes burgeoned to serious poignancy and became almost too gorgeous to stand.

At Neumos, Egyptrixx began his set with an awesome onslaught of scouring drone more akin to a psychedelic-noise act than a techno producer. After about five minutes of this, brisk beats entered earshot, but Egyptrixx kept the underlying textures weird; it was as if NYC equilibrium-subverters Black Dice were collaborating with acid-techno kingpin Audion.

• oOoOO at Crocodile: Smoking mad.

The Crocodile was packed for Star Slinger, whose major-key instrumental hip-pop did nothing for me, but the crowd kind of slimmed for oOoOO, an artist I was stoked to see. He came on looking totally unlike what I expected: fitted ballcap, white wifebeater, gold chain. Dude seemed outfitted for the (defunct) Yo, Son! weekly, not a witch-house concert. His backing video consisted mostly of footage glamorizing cigarette smoking, which is a stupid, self-sabotaging habit you should never pick up. oOoOO positioned sluggish, mainstream-hiphop beats into a mournful, icy, drifting atmospheres. He conjured a woozy stew of opiated sound, which included a snippet of Lady Gaga’s “Poker Face,” menacingly pitched down. Some more people filtered out. They weren't feeling the Warm Oscillations, I guess.

At one point, oOoOO lit a cigarette onstage; less than a minute later, a Croc employee walked over and confiscated it. oOoOO didn’t seem too happy about this. About 30 minutes into his set, he simply walked off in the middle of a track. Shortly after, the house lights went up. I’ve contacted Decibel director Sean Horton to try to find out why oOoOO bounced 30 minutes before his performance was slated to finish.
