Class of '94.
For my friends and I, it was Nirvana without question.
"Nevermind" dropped a few weeks before I got my driver's license, and when that happened the musical landscape changed virtually overnight. We were listening to the Edge back then, and Nirvana's harder sound opened the door to other acts and pushed the "college rock" bands like REM out of the Alt-rock spotlight. But the real difference was in the programming on more mainstream stations, like Q-102. Or how MTV's programming became a lot like an extended version of 120 minutes.
