PREVIEW In the liner notes to his Automatic Writing (Lovely Music, 1996), Robert Ashley talks about how he tried to source text for his 1967 opera That Morning Thing by soliciting recordings from his friends narrating, without psychological or moral interpretation, scenes from their life that they'd chosen to keep secret. Describing the results of his survey as "very bad," Ashley decided to synthesize his own text, the result being the viscerally creepy "Purposeful Lady Slow Afternoon."
The mercurial earth-mother drones of Inca Ore the solo moniker of Oakland's Eva Saelens have, in their blown-out glory, a circuitous sonic relationship with the whining Moog ambience of Ashley's strangest music, and the raw psychic effects of last year's Birthday of Bless You (No Fun) are comparable to the composer's work. Leaping from the absolutely banal to the densely metaphysical, Bless You's world is psychology- and morality-free, and when words replace bodiless moans, the effect is evocative, occult, and informed by a slight but potent sense of self-parody. As she declaims through a delay pedal at the conclusion to scrape-scape "Infant Ra": "to all jewels buried in the grass, awake, discovery, in oyster shells!" It's not a hard world to get sucked into.
INCA ORE With Mangled Bohemians, and the Why Because. Wed/14, 9 p.m., $6.
