San Francisco producer Pure One (Alexandra Crotta) utilizes her voice as an instrument in her experimental electronic compositions. On many of her tracks, she manipulates her soft, cooing vocals beyond recognition, chopping them up and layering them until they take on fuzzy textures and warped shapes. Throughout “Melchedezek, My Love,” one of her latest tracks, she murmurs lyrics that evoke spontaneous word associations: Let’s go on/Let’s go to war/Let’s go to her. Her repetitive, whispered verses become a haunting mantra that washes over a slow, ambient beat, foregrounding the warbled, ebbing and flowing of her synth. Pure One’s tracks are subtle and atmospheric, and while many of them use hip-hop and trip-hop beat structures as a starting point, they often unravel into avant-garde, electronic sound collages. Pure One is a relatively new music project, and she is releasing her debut EP later this month. She performs at Stork Club on November 14 with producer LoWGritt and indie band Arrows, both from Santa Cruz, as well as Oakland noise rockers Knowles Hand.
