8. Nirvana, 'Bleach'
Nirvana's Bleach didn't usher in a musical revolution when it hit shelves in the summer of 1989. This was the era of Paula Abdul, Mötley Crüe and Bobby Brown, and there wasn't anything resembling a mainstream audience for gritty songs like "Negative Creep" and "Blew." But the group was hardly aiming for MTV. Though they disliked the term "grunge," they were a key part of a Seattle underground music scene that had yet to be detected by the masses. "For a few years in Seattle, it was the Summer of Love, and it was so great," Cobain told Rolling Stone shortly before his death. "To be able to just jump out on top of the crowd with my guitar and be held up and pushed to the back of the room, and then brought back with no harm done to me – it was a celebration of something that no one could put their finger on." They cut Bleach in just 30 hours. Despite very warm reviews, it didn't find much of an audience. It took the success of Nevermind a couple years later for fans to go back and realize they had missed out an on absolute classic.
