It turns out that that one-off Black Flag concert scheduled to take place at this year's Hevy Fest in England isn't a one-off appearance after all. Last week it was announced that the 1979 line-up of the legendary punk band was reuniting for the U.K. event, and now comes news that the same formation is recording a new album and will mount a U.S. tour in 2013.

The group's plans were revealed in a press release reported on Brooklyn Vegan, although full tour and album details have not yet been announced. The release states:

Black Flag has reformed and is in the process of putting finishing touches on a new album with founder Greg Ginn on guitar, Ron Reyes on vocals, Gregory Moore on drums and Dale Nixon on bass.

While Dale has lent his skills to the new album, he is currently contractually obligated for a stint on 'Celebrity Rehab.' Still, as he has always done in the past, he will continue to provide insight and spiritual guidance to the current bass player.

That whole 'Celebrity Rehab' bit is an inside joke, because "Dale Nixon" is merely a pseudonym Ginn has used when recording bass parts for Black Flag on various Black Flag albums. In other words, Ginn likely plays bass on the new album and will be replaced by another musician to be announced for live performances.

The only confirmed U.S. gig for the reformed Black Flag is an Aug. 31 appearance at the Muddy Roots Music Festival in Tennessee. Additional dates and album details are expected to be announced soon.

In related news, former Black Flag members Keith Morris, Chuck Dukowski and Bill Stevenson recently announced that they had formed a group called FLAG that has lined up a handful of summer tour dates in Europe, with a U.S. trek expected to be revealed soon.
