Pink Floyd have released the music video for "Louder Than Words," a cut from their recently released album, The Endless River.

The video, directed by Po Powell, features the band working on the track in the studio.

Other scenes in the visual were captured by Powell during his trip to the Aral Sea on the border between Kazakhstan and Uzbekistan.

"A surreal image if ever I saw one, and a shocking example of human mismanagement and one of the planet's worst environmental disasters . . . The river has shrunk to 10 percent of its original size, destroying the fishing industry and whole townships."

"Louder Than Words" is the only cut on The Endless River that features lyrics.

David Gilmour says that Endless River will likely be the band's last effort.

"I don't see how to could be otherwise," he said. "Anything of value is on The Endless River.

Trying to do it again would mean using second best stuff. That's not good enough for me."
