From notes on the back cover:

"This album interpolates, edits and manipulates music originally made by Bogusɬaw Schaeffer. We are grateful to Michael Mendyk of the Adam Mickiewicz Institute in Warsaw for proposing that we work with Schaeffer’s music, and for securing the permission of the Schaeffer estate that allowed this project to crystallize. We have not played his music, but we have played with it and created new songs from fragments of many of his works, created originally at the Polish Radio Experimental Studio in the 1960s and 1970s. The sources are: Monodram, Heraklitiana, Theme: Electronic Music, Music for Tape, E.S. Jazz, Symphony: Electronic Music, Missa elettronica, Project, Antiphona, Assemblage I and Assemblage II."

Financed by the Ministry of Culture and National Heritage of the Republic of Poland as part of the multimedia annual programme Niepodlegla 2017-2022.

THANK YOU: First and foremost, thanks to Bogusɬaw Schaeffer for his music, to the musicians who played on this recording, to Michal Mendyk and all at the Adam Mickiewicz Institute for commissioning this work, to Bettina Richards and all at Thrill Jockey, Mat Schulz and Gosia Pɬysa and all at Unsound Festival, Andy Battaglia, Philip Sherburne, Nikita Lavrinenko, Mickey Darius, and all of our friends.
