There have been at least 6 bands under name Bulldozer: 1) Bulldozer is an Italian speed/thrash/proto-black metal band formed in 1980. Their music was frequently referred to as Italy's answer to Venom, and on the strength of their debut album, 1985's "Day Of Wrath" (produced by Algy Ward of Tank), it's easy why this was the case. Alberto Contini's bass and vocals both strongly resembled his Venom counterpart Cronos, and the band's messy Satanic pre-thrash metal was indeed quite similar to Venom's first couple of albums.
