There are more than one band under this name: 1) Harbinger is a band formed in 1997 in Berkeley, California featuring three prominent members from the East Bay punk scene: Robert Eggplant (vocals/guitar), formerly of Blatz, The Hope Bombs, and editor of the zine Absolutely Zippo, Aaron Cometbus (drums), founding member of Crimpshrine and author of legendary punk zine Cometbus, John Geek (bass/vocals) of Fleshies and the S.P.A.M.

Holy Grail consists of White Wizzard alums James Paul Luna, James J LaRue and Tyler Meahl, along with the blazing co-shred guitar of Eli Santana and the thunderous deathblow of bassist Blake Mount. In smoldering cauldrons of wicked brutality, Holy Grail combines elements of NWOBHM, Shred, Thrash and Doom featuring unmatched vocal domination and guitar astro-technics. Their debut album titled Crisis in Utopia was released on October 22nd, 2010 via Prosthetic Records.

Motörhead are a British hard rock band formed in 1975 by bassist, singer and songwriter Lemmy Kilmister, who has remained the sole constant member.
While Motörhead are typically classified as heavy metal, speed metal or thrash metal (and often regarded as a foundational influence on the later two styles), Lemmy dislikes such labels, preferring to describe the band's music simply as "rock n' roll".

Megadeth is an American thrash metal band led by founder, frontman, guitarist, and songwriter Dave Mustaine. Formed in 1983 Los Angeles, California with bass player Dave Ellefson following Mustaine's departure from Metallica, the band has since released twelve studio albums, six live albums, two EPs, thirty singles, thirty-two music videos, and three compilations. As a pioneer of the American thrash metal movement, Megadeth rose to international fame in the 1980s, but experienced numerous line-up changes, due partly to the band's notorious substance abuse problems.
