Here's a link we love: MentalFloss.com wrote up the stories behind 11 classic album covers. (Remember back when they really were albums?)
Some of these histories you've heard before. You may already know that the peelable sticker on the banana on the Andy Warhol-designed "The Velvet Underground & Nico" had to be painstakingly applied by hand. And you probably have seen at least one interview with Spencer Elden, who in 1991 was the swimming four-month-old baby shown on Nirvana's "Nevermind."
But the MentalFloss story digs up some fascinating facts I didn't know about other classic covers.
Members of The Who didn't really, um, self-water that concrete piling on the cover of 1971's "Who's Next," but not for lack of trying. The site quotes photographer Ethan Russell as saying "Most of the members were unable to go, so rainwater was tipped from an empty film canister to achieve the desired effect."
The prism on Pink Floyd's 1973 "Dark Side of the Moon"? Came from a school textbook.
The Joshua Tree on the cover of U2's 1986 album of the same name? Died in 2000, but fans have marked its California desert location with a shrine.
Other album covers explained in the fun list include The Clash's "London Calling," the Beastie Boys' Licensed to Ill," and Beck's "Odelay."
