Black Flag's first studio album in almost three decades is available to stream on Spotify today, an entire month before the album's official release.

Despite not being due to be released until December 3, the 22-track long What The... is also available on streaming website Rdio (U.S. only).

The release of What The… sees Greg Ginn reunite with Ron Reyes, Gregory Moore and Dave Klein to complete the line-up.
