On May 15th, Pantera's Vulgar Display Of Power will be re-released and remastered for the albums 20th anniversary.  As it been that long?  The deluxe set will include a live set fro Italy in 1992 and three official videos.  But what Pantera fans will be salivating over is the unreleased track "Piss" that will be included.  Vinnie Paul recently found the track while going through the Patnera vault.  Is there anything else in there he would like to share with us?  The 15 second teaser for "Piss" is below.
