On February 25, Pantera’s classic album Vulgar Display Of Power will turn twenty years old. And considering how the album spawned the band’s biggest hit “Walk,” as well as other staples like “Mouth Of War,” “Fucking Hostile” and “This Love,” it’s no surprise that the album will receive the “20th Anniversary reissue” treatment similarly given to Cowboys From Hell. And just like that reissue (which included the demo track “The Will To Survive”), the Vulgar Display Of Power 20th edition version will include a previously unreleased track called “Piss.”

In a recent interview with LoudWire, drummer Vinnie Paul recalled the song’s origins and why it got shelved, saying the following:

“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.”

Though it’s still unclear as to when exactly the Vulgar Display Of Power 20th Anniversary reissue will be released, fans have likely already heard a snippet of “Piss.” A sample of the song was featured in an episode of Jose Margin’s re-launched Headbangers Ball at the end of 2010. In case you missed it, you can listen to the short taste of “Piss” (ed note: ewww) after the jump.
