Works (1983)

The release of "Works" in 1983 would have been an entirely insignificant occurrence, if not for the inclusion of one new composition in this collection of otherwise previously released songs.

"Embryo" was actually recorded by Pink Floyd during the sessions for 1969's "Ummagumma" album. However, since the song was recorded by the group, and thus didn't fit into the album's concept of providing time for each band member to do his own thing for a half of an album side, its release was put on hold.

The song would eventually be issued in 1970, as part of "Picnic," a sampler compiled by the Harvest label, even though Roger Waters, the number's author, says that the song was never truly finished. Its inclusion on the "Works" album some 13 years later surely made it available to a wider audience, and boosted sales for the album.
