BLACK HAT, WHITE BOY SCREAM + VIVIANE JAMES, BAT

Freak fests of this caliber are a rarity, and tonight's lineup should send experimental-music heads spinning into a frenzy of sheer decapitated excitement. Black Hat (Nelson Bean) conjures a melodic machine takeover through primordially ambient IDM. His latest EP, Covalence (Field Hymns Records), pulsates with warbled, mountainous textures, a gritty industrial electronic fun-house tour that distorts perception in freakier-than-expected ways. As White Boy Scream, Micaela Tobin's gorgeous, classically trained opera voice mutates into Auto-Tuned Satan, with hiccuping, reverberating synths beneath. New Cairo music curator/longtime awesome person Viviane James (Footwork, Wet Paint DMM) will be adding to her set with performance art that may make you even more uncomfortable, as the best performance art does. With Bat, solo project of local noise-punk force Health Problems' Ian Kurtis Crist, a wild descent into post-punk experimentation. Teatro de la Psychomachia, 9 pm.

LANDLINES, SAN ONOFRE LIZARDS, IJI, PILL WONDER

Pill Wonder's 2010 LP Jungle/Surf was the first album I ever preordered (d'aww), and since that under-heralded local classic, the pervasive pop sensibility of bandleader Will Murdoch has taken plenty of different forms, but always to delightfully hook-laden effect. Seattle's neon-infused bedroom-pop standbys iji will bring forth endlessly sunshiny keyboard pop perfect for mellow Jazzercise or making out in a closet, while Portland indie-rock ensemble Landlines are doing the slacker thing (their latest release: the Loserly EP), slightly dazed and (shoe)gazed. From the evocatively reptilian San Onofre Lizards, expect psych-hued "caveman rock 'n' roll" with members of the Family Stoned and Dana Jewel. Lo-fi-pop-elujah! Heartland, 8 pm.

CHRISTIAN MISTRESS, OCCULT SS, PARALYZER

As the current occupants of Olympia's throwback '80s British heavy-metal throne, Christian Mistress reign with powerfully punk authority. Led by the powerhouse vocals of Christine Davis, the brutalitarian four-piece crusades through a furiously retro, arena-sized brand of heavy metal. Adding to the night's destruction, Occult SS will drag you by the ear into their crust-lined hellfire of putrid punk with charming ditties like "Heathen Blood" and "The Final Hammer." Raise your blood-encrusted goblets! Black Lodge, 9 pm.
