Which of these bands is not associated with the New Wave movement of the 80s?

Metallica

Formed in 1981, Metallica is frequently cited among the "Big Four" of thrash metal, standing out alongside bands such as Slayer, Megadeth, and Anthrax. Contrary to the New Wave and synth-pop sounds characteristic of the 80s, Metallica carved its own path in the heavy metal universe. Their impact on the music industry has been considerable, notably with landmark albums like "Master of Puppets," which not only defined their unique sound but also set a new standard for the genre.
