NIRVANA’S lead singer, Kurt Cobain, is pictured here during his brief career in the early 1990s. The release of Nirvana’s Nevermind in September 1991 bumped Michael Jackson’s Dangerous from the top of the charts and signaled a new direction in popular music. Other grunge bands soon followed Nirvana onto the charts, including Pearl Jam, Alice in Chains, Stone Temple Pilots, and Soundgarden.© Pycha/DAPR/Zuma Press
