Roots of Puritanical Euphoric Misanthropia

Hellhammer was a Swiss extreme metal band from Nürensdorf, active from 1982 to 1984. Although the band's sound and style were heavily criticized and poorly reviewed during their active years, they have been widely praised in retrospect and are often regarded as a key influence on black metal. In June 1984, Hellhammer disbanded but two of its members soon formed the influential extreme metal band Celtic Frost.

Pantera is an American heavy metal band formed in Arlington, Texas, in 1981 by the Abbott brothers, and currently composed of vocalist Phil Anselmo, bassist Rex Brown, and touring musicians Zakk Wylde and Charlie Benante. The group's best-known lineup consisted of the Abbott brothers along with Brown and Anselmo, who joined in 1982 and 1986, respectively. The band is credited for developing and popularizing the subgenre of groove metal in the 1990s. Regarded as one of the most successful and influential bands in heavy metal history, Pantera has sold around 20 million records worldwide and has received four Grammy nominations.
