Neil Young says the soundtrack to the forthcoming Crosby, Stills, Nash and Young documentary "CSNY: Deja Vu" constitutes the best album ever made by the legendary supergroup.

"It's CSNY," he told Billboard recently during a lengthy interview about the new film. "It really is CSNY. It's not overdubbed. There's no fixes. It's straight from the board."

The documentary will hit U.S. theaters July 25 simultaneous with its home video and retail release. The soundtrack is due July 22 via Reprise.

"Deja Vu" was captured on CSNY's 2006 Freedom of Speech tour, during which the band often split audiences along party lines while delving heavily into its protest songs and the balance of Young's then-new anti-war album "Living With War."

"The basic mixes are the mixes that people heard when we were playing it," Young continues. "So it's got rough spots all the way through it, which I think is refreshing, especially considering the subject matter. Why should we polish? Why polish this? Who gives a shit whether it's polished or not? It is what it is, and that's the message of the music. It's what we're doing. If you don't like, you don't like it. If you like it, you like it. But it is what it is. Chroming it is not going to help it."

The thinking, Young said, was that the more raw the soundtrack is, the better they will sound and the more exciting it will be. "And nobody's heard that from CSN," he said.
