Restoration Ruin is an album by Keith Jarrett on which he performs multiple instruments, and sings his own lyrics. Recorded and released on the Atlantic Records subsidiary Vortex in 1968, the album remains unique in Jarrett's catalogue, displaying a sound largely influenced by folk and progressive rock. It can be seen as the first part of an experimental period which explored neither traditional jazz nor classical music. Here Jarrett overdubs himself on various instruments, similar to the tribal Spirits (1985) or especially the free funk No End. "Sioux City Sue New" was released as a 45 rpm single, backed with "You're Fortunate." In 1999, Collectables Records reissued the album paired with the Art Ensemble of Chicago's Bap-Tizum.
