The iconic prog-rock band Pink Floyd will release its first album in 20 years this coming October, according to the wife of band member David Gilmour.

Polly Samson tweeted that the new album will be called The Endless River and is based on sessions recorded in 1994, the year the band’s last studio album, The Division Bell, was released.

She also described the new release as the “swansong” of Rick Wright, the band’s keyboard player who died in 2008 at the age of 65. It was initially unclear whether Samson’s definition of “swansong” meant that the new album would be entirely based on old 1994 material or whether it would feature more recently recorded contributions, as Wright continued to record solo material after The Division Bell, according to the Los Angeles Times.

Columbia Records confirmed in a statement on Monday the October release of The Endless River and said it was “mainly ambient and instrumental music” from 1993 and 1994 but that it was “still in progress.”
