It features Oneontrix Point Never, Yo La Tengo, Giant Swan, Marisa Anderson and more, all synchronised at a steady tempo of 99 beats per minute.

The resulting album is a three-hour long assemblage that travels across a shifting kaleidoscope of genre, mood and density, all synchronized to a constant underlying tempo.
