Speaking in a recent intervie wwith Music Mania, Testament frontman Chuck Billy explained his thoughts about the Big Four. Why his band wasn’t included in “Big Four”, he stated:
“Well, it’s difficult to say, ’cause when you say ‘Big Four,’ you think of the ’80s when that was what was referred to as the ‘Big Four,‘ which is correct — those four bands [METALLICA, MEGADETH, SLAYER and ANTHRAX] were the biggest four bands of our era; at that time, all [of them were] at the platinum level, when there was much more acceptability to this music.
Around ’91 [or] ’92, the grunge scene came in, and all the bands following us — EXODUS and OVERKILL and all those kind of bands — lost that momentum because the industry started changing its format.
So when they say [METALLICA, MEGADETH, SLAYER and ANTHRAX are the] ‘Big Four,’ I say that’s correct. We were the next generation of the ‘Four’ [laughs], but we were just caught in the wrong time… wrong place, wrong time.”
