When it was released in 1991, Nirvana’s Nevermind sent shockwaves through the music world. It brought alternative rock to the mainstream and almost overnight made Nirvana the biggest band in the world. The record went on to sell over 30 million copies and is widely considered to be one of the greatest albums of all time. Part of Nevermind’s success was almost certainly due to its incredible cover, created by Robert Fisher.
