Grayfolded is a two-CD album produced by John Oswald featuring the Grateful Dead song " Dark Star". Using over a hundred different performances of the song, recorded live between 1968 and 1993, Oswald, using a process he calls " plunderphonics", built, layered, and "folded" all of them to produce two large, recomposed versions, each about one hour long.
The first disc of Grayfolded, titled Transitive Axis, was released in 1994, and the second disc, Mirror Ashes, was released in 1995, both on the Swell/Artifacts label. The two discs were released together in 1996. Grayfolded was re-released by Snapper Music in 1999, and by Fony in 2004. It was released as a three-disc vinyl LP on August 12, 2014, on the Important Records label.
Grayfolded is one of only three Grateful Dead albums that features the participation of every musician who was ever in the group, the others being the box sets So Many Roads (1965–1995) and 30 Trips Around the Sun (as well as the latter's 4-disc version).
