DEF LEPPARD's breakthrough 1983 album, "Pyromania", has been certified at the RIAA's (Recording Industry Association of America) diamond level (10 million copies shipped) last month, according to Billboard.com. Produced by Robert John "Mutt" Lange, "Pyromania" benefited greatly from MTV's relentless airing of the album's first two singles, "Photograph" and "Rock of Ages". The U.K. group continues to record and tour, their most recently release being 2002's "X" (Universal).

Also reaching new multi-platinum heights in July was PANTERA's "Vulgar Display of Power" (Elektra), which was certified double-platinum by the RIAA, signifying shipments of more than 2,000,000 units in the U.S. since its February 25, 1992 release.

Widely considered to be one of the most influential metal albums of the 1990s, "Vulgar Display of Power" revitalized thrash metal, mixing crushingly heavy grooves and rhythms with a harder-edged vocal approach. "Walk" and "Fucking Hostile" remain two of PANTERA's best-known songs.

"Vulgar Display of Power" peaked at No. 44 on The Billboard 200 album chart, according to Wikipedia.
