Blue Abstraction compiles a selection of Jessica Williams' lost prepared piano recordings. These recordings document the beginning of a vital, solitary phase in her career: a period of intense sonic experimentation that began with physically altering a 6'4" grand piano -- creating a new instrument, and from there, creating a new music. The results are breathtaking; from melancholic soundscapes with Satie-esque lyricism to forcefully controlled cacophony, always grounded by the distinct emotional voicing of her melodic lines. Jessica Williams (1948-2022) was a pioneering trans jazz pianist and composer from Baltimore, where she studied at the Peabody Conservatory. Among countless other greats, she gigged with Philly Joe Jones, Dexter Gordon, Stan Getz, Tony Williams, Charlie Rouse, Jackie McLean, Roy Haynes, Charlie Haden, and Bobby Hutcherson, and recorded with Eddie Henderson, Eddie Harris, Leroy Vinnegar, Victor Lewis, and Ray Drummond. She received accolades from piano greats McCoy Tyner and Dave Brubeck. Williams could play anything and knew the standards deeply -- expanding from there through her composing and arranging. In 1985, with a head full of Thelonious Monk's dissonant harmonies, Williams began her prepared piano project. She altered the piano by placing vibrating and/or muting elements on top of and between the strings at varying distances across the harp -- some sounding like bells or gongs (screws, bolts), others like percussion instruments (clothespins, hairpins, washers, erasers). The effect radically expanded the instrument's possibilities, sometimes making it sound metallic or ghostly, other times muted, tactile, almost broken. The resulting beauty and listenability of these works are a testament to Williams' vision and mastery. The recordings on Blue Abstraction came out of three years of experimentation. She recorded at her own Quanta Studios and at Moon Studios (both in Sacramento), and two live performances at Noe Valley Ministry in San Francisco, on January 11 and May 10, 1986, as part of the Noe Valley Music Series. For Williams, these recordings were a personal transformation through the musical process. Though known for her recordings and live performances -- especially of Monk tunes -- Williams made some of her most forward-thinking music privately. The music on this record disappeared for almost four decades.
