Billed as C. Spencer Yeh’s ‘first true solo album’, 1975 is an investigation of static drone works that forsakes the kinda barbarous dynamic violence of Burning Star Core for a series of luminous/ghostly tonal settings that coil like smoke around your skull w/deep fields of searchlight tone and jabbering cut-up detail. Buncha different sound sources flagged in the self-explanatory titles – “Two Guitars”, “Voice”, “Drone”, “Shrinkwrap from a Solo Saxophone CD (skit)” – with the music moving from tactile almost Philip Corner-esque miniatures through endlessly glissing xpressways of soft feedback that mirror the stately, surreal arc of Nurse With Wound’s Soliloquy For Lilith. One of Yeh’s most immersive and form-gobbling works, play this back to back with BXC’s Challenger for a lesson in the dynamic possibilities of killing time dead. Recommended.
