Question: In what year did Hellhammer become Celtic Frost? Passage:Welcome to Hell influenced several later bands. Venom's music helped shape the development of many thrash metal bands, specifically the "Big Four of Thrash" (who in turn were highly influential): Metallica, Slayer, Anthrax, and Megadeth (Metallica opened for Venom on an early 1980s tour, and Venom opened for Metallica and Slayer on the Ride the Lightning tour, and Slayer played with them and Exodus on the Combat Tour in 1985). Venom would also be of extreme importance to the black metal scene and even the early death metal scene, with numerous bands copying styles, themes, and imagery from the band, such as the Swiss band Hellhammer (later to become Celtic Frost), whom also helped pioneer the genres. Music critic Bradley Torreano wrote that Venom "caught the attention of both metalheads and punks, the band was emulated by the former and turned into camp icons by the latter." Henry Rollins once compared the band to Spinal Tap.
