would form his own endeavor, Autopsy, which has also been regarded as an early inspiration of the death metal genre. Autopsy's 1989 debut, Severed Survival, would feature bassist Steve DiGiorgio, founder of Antioch, California thrash metal band Sadus; Schuldiner had also met DiGiorgio while living in the Bay Area, who would play bass for Death on the albums Human and Individual Thought Patterns. Musical characteristics Influences As different thrash metal scenes developed around the world throughout the 1980s, each had their own distinct style and influence. Several early luminaries of the Bay Area scene borrowed heavily from the new wave of British heavy metal and early punk rock: Exodus guitarist Gary Wayne Holt mentioned discovering Tygers of Pan Tang, Diamond Head, Trauma, Angel Witch, Venom and Budgie on a KUSF radio show hosted by Ian Kallen and Ron Quintana. Hammett, Hetfield and Ulrich have also cited Venom and Budgie as important influences, in addition to punk acts like the Misfits, Charged GBH and Discharge. Albums that very much reflected this era and inspiration include Kill Em All and Bonded By Blood. Other bands, such as Attitude Adjustment, took the hardcore punk influence to a greater extent, with the aforementioned group involving former musicians from Agnostic Front, D.R.I., and Murphy's Law during their line-up history, in addition to show dates at 924 Gilman, a Berkeley venue more oriented to hardcore punk than heavy metal music. Attitude Adjustment's style, "crossover thrash", a grindcore precursor, would influence many bands of the latter subgenre, including chief innovator, the British band Napalm Death, who would cover Attitude Adjustment's "Dope Fiend" and Hirax's "Hate, Fear, and Power" on an exclusive covers album (coincidentally, the Hirax track had featured Attitude Adjustment drummer Eric Brecht on the original 1986 recording). Hirax, while Orange County, California-based, had many connections to bands of the Bay Area thrash scene, as the group had played at Ruthie's Inn, and in past line-ups, featured Paul Baloff (formerly of Exodus and Heathen) and Ron McGovney (Metallica's first bassist). Long Island-born multi-instrumentalist Joe Satriani had relocated to Berkeley, California, in 1978 to pursue a career teaching music; although he was mainly influenced by blues rock and had not specialized in heavy metal music initially, many of Satriani's students would go on to become progenital guitarists in the Bay Area metal scene, including Kirk Hammett of Metallica/Exodus, Larry LaLonde of Possessed, Alex Skolnick of Testament, Rick
