Pentiments continues its collaboration with the legendarily enigmatic American sound art pioneer Leif Brush, this time with an extensive double LP release representing the most comprehensive collection of his recorded work to date. In plumbing the depths of his archives, we’ve unearthed and gathered a great breadth of his decades-long sonic research, spanning from his early work as a grad student to various lecture documents from his eventual tenure at UMD, with many curious stops and experiments in between.

“Stitching in Process: Windmixed Data” brings these fragments together with a somewhat new perspective on their trajectory—pieces are reconsidered, refreshed, and given a new sense of continuity, aided additionally by the expert mastering of Giuseppe Ielasi. Most importantly, this release marks the first commercially available compendium of Leif’s greater body of work in his 85 years of life, and for those keen on the early exploration of sound and its potentials, it is a revelation that is long overdue. In an edition of 200 with high gloss gatefold sleeve featuring the photo work of Gloria DeFilipps Brush.
