From 1974 until 1985, the band consisted of guitarist Eddie Van Halen, vocalist David Lee Roth, drummer Alex Van Halen, and bassist Michael Anthony . </P> <P> The band went on to become major stars, and by the early 1980s they were one of the most successful rock acts of the time . 1984 was their most successful album .

Former Extreme frontman Gary Cherone was quickly recruited as lead singer to replace Hagar, and Van Halen III was released in 1998 .
