A Monday news release gives fresh details about The Endless River, the British rock 'n' roll group's first new material in 20 years.
The 18-song double album features Pink Floyd members David Gilmour, Nick Mason and Richard Wright, who died in 2008. Roger Waters left the group in 1985 and isn't involved.
The album was assembled from 20 hours of material recorded during the band's 1993 sessions for The Division Bell.
Gilmour says in the release that the band "added new parts, re-recorded others and generally harnessed studio technology to make a 21st-century Pink Floyd album."
The Endless River is comprised mostly of instrumental music with just one song, Louder Than Words, that includes new lyrics, written by Gilmour's wife, Polly Samson.
