Pantera recently announced that their only unreleased song would be included as part of the 'Vulgar Display of Power' 20th anniversary reissue -- get a sneak peek at the track 'Piss' here.

Pantera are set to release the 20th anniversary reissue of one of metal's most celebrated albums on May 15th. The reissue will come with a DVD as well as the only track the band never made public -- 'Piss.' Vinnie Paul previously explained the story behind the Pantera oddity:

"The reissue has a song called ‘Piss,’ which I had forgotten about it. Some parts of it were taken for other songs, and at the time, it was the only song that did not make the record. In Pantera, we never had songs that didn’t make the record. If we were going to write 11 songs, then we’d write 11 quality songs. Some bands write 40 songs and then hope they have nine good ones in the bunch. That sucks. Why not concentrate on writing 9 great ones and forget the 31 others? Anyway, this song, at the time, didn’t feel right to go on the record, so we put it on the shelf. When I started digging through archives, we were happy with it. It is the only undiscovered complete Pantera track there ever was and it will be part of the package. It should be cool to hear the first new thing from the band since 2000.”

The lost 'Vulgar Display of Power' track rounds out the deluxe edition package which also comes with a DVD showcasing ultra rare footage of the band's 1992 Monsters of Rock performance in Italy. For a full tracklist of the disc and DVD click here.
