Today (Feb. 25) marks the 25th anniversary of the release of Pantera's groundbreaking Vulgar Display of Power. In honor of it, our sister site Loudwire has created a three-part documentary about the making of the album.

In the first part, the three surviving members of the group -- Phil Anselmo, Vinnie Paul and Rex Brown -- and producer Terry Date share some stories about the sessions, including how Anselmo and "Dimebag" Darrell Abbott needed to "get on the same wavelength" (i.e., get stoned together) in order to record "A New Level."

For the second part, they spoke with numerous musicians, including Dave Mustaine, Mike Portnoy and Kerry King, about the record's influence, from how it revitalized metal, which had been left for dead in the wake of grunge. with each member of Pantera being singled out as influencing future generations of metal musicians, with the greatest praise reserved for Anselmo's vocals and Dimebag Darrell's guitar playing. "They had shred," said Megadeth's David Ellefson. "They had Phil as the angry singer, and then they had this groove swagger. So they had three really key components that kinda changed the course of where heavy metal went." Portnoy, for his part, compared it with AC/DC's Back in Black and Van Halen's debut as albums that are "perfect."

The third segment describes the making of the cover, with photographer Brad Guice, now a pastor in New Jersey, recounting what they wanted, and they debunk the myth that they paid a homeless man $10 per take to get punched in the face. Guice said that it was a prodessional model and while Paul and Brown differ over the number of times he was punched, Guice says that it was a staged shot.

Loudwire have set it up as a playlist, with more footage from the interviews following the third part. You can watch all of it above.
