Rock diversifies in the 1980s

In the 1980s, popular rock diversified. This period also saw the New Wave of British Heavy Metal with bands such as Iron Maiden and Def Leppard gaining popularity. The early part of the decade saw Eddie Van Halen achieve musical innovations in rock guitar, while vocalists David Lee Roth (of Van Halen) and Freddie Mercury (of Queen as he had been doing throughout the 1970s) raised the role of frontman to near performance art standards. Bono of U2 would continue this trend. Concurrently, pop-New Wave bands remained popular, with performers like Billy Idol and The Go-Go's gaining fame. American heartland rock gained a strong following, exemplified by Bruce Springsteen, Bob Seger, Donnie Iris, John (Cougar) Mellencamp and others. Led by the American folk singer-songwriter Paul Simon and the British former prog rock star Peter Gabriel, rock and roll fused with a variety of folk music styles from around the world; this fusion came to be known as "world music", and included fusions like aboriginal rock. Also, more extreme forms of rock music began to evolve; in the early eighties, the harsh and aggressive thrash metal attracted large underground audiences and a few bands, including Metallica and Megadeth, went on for mainstream success.
