Time for die-hard Pink Floyd fans to go crazy. The iconic rock band is reportedly set to return this fall with its first new album in 20 years.

That is, according to this tweet from Polly Samson, wife of lead singer-guitarist David Gilmour. Samson casually announced the new album, titled "The Endless River," will be released in October. (ViaTwitter / @PollySamson)

And as you can imagine Pink Floyd loyalists were caught a little bit off-guard by the seemingly offhand announcement.

In her tweet, Samson also said the new album is a "swansong" -- or tribute -- to the band's keyboard player Rick Wright, who died in 2008. (Via Youtube / PLANx)

Los Angeles Times points out that everyone is still kind of left in the dark -- ahem, side of the moon -- as to what exactly the project will entail.

It could be unreleased recordings from their last album or some of Wright's solo work afterward. (Via Getty Images)

Though Rolling Stone said "The new material appears to be connected to unreleased recordings made during the Division Bell sessions," and points to --Durga McBroom-Hudson, a singer who toured with the rock group during the 1980s and 1990s, and who revealed a few more details about the upcoming album on her Facebook page.

"The recording did start during The Division Bell sessions ... which is why there are Richard Wright tracks on it. ... It was originally to be a completely instrumental recording, but I came in last December and sang on a few tracks." She also said the new album will be composed entirely of unreleased material.

That would at least seem to make sense, as Pink Floyd is fresh off celebrating the 20th Anniversary of that 1994 album, "The Division Bell," with a huge reissue on July 1. (Via Youtube / HDPinkFloyd)

People also said it's still up in the air if ex-Floyd bassist Roger Waters will join in on the reunion album. Waters is mostly credited with the giving the band its unique sound, but he and Gilmour are reportedly not on the best terms.

And, without Waters, who knows? It might just be another brick in the wall for the recording industry. Who are we kidding? It's Pink Floyd!
