Back in the '70s, a group of rock & roll carousers called themselves the Hollywood Vampires as they crawled the bars of Los Angeles during the dead of night. Alice Cooper was at the forefront, joined by Harry Nilsson, John Lennon, Ringo Starr, Keith Moon, and Micky Dolenz -- a crew so soused that their tales became legend, even if the specifics of the debauchery were often forgotten. Forty years later, Alice Cooper revived the name Hollywood Vampires when he formed a classic rock supergroup with Joe Perry and Johnny Depp. In the spirit of the original Hollywood Vampires, a bunch of other stars were invited to play on the group's eponymous 2015 album.
