Hagar stayed with the band longer than Roth, helping the group top the charts through the late '80s and early '90s. One of these was Sammy Hagar, an arena rock veteran from the '70s who replaced Roth after the vocalist had a falling out with Van Halen in 1985.

Furthermore, Roth's irony-drenched antics were copied by singers who took everything literally. Throughout the '80s, it was impossible not to hear Van Halen's instrumental technique on records that ranged from the heaviest metal to soft pop. Together, they made Van Halen into the most popular American rock & roll band of the late '70s and early '80s, and in the process set the template for hard rock and heavy metal for the '80s. Roth wasn't blessed with great technique, unlike Eddie, but he had a flair for showmanship that was derived as much from lounge performers as Robert Plant. It was wildly inventive and over the top, equaled only by vocalist David Lee Roth, who brought the role of a metal singer to near-performance art standards. Guitarist Eddie Van Halen redefined what electric guitar could do, developing a blindingly fast technique with a variety of self-taught two-handed tapping, hammer-ons, pull-offs, and effects that mimicked the sounds of machines and animals (see his rig). With their 1978 eponymous debut, Van Halen simultaneously rewrote the rules of rock guitar and hard rock in general.
