When was Nevermind released?

I can't really remember the first time I actually heard Nirvana. Was it a rapturous moment, where I knew, right then and there, that music had been changed forever? Or was it just another band that my brother listened to?

Today this album is revered as seminal, ushering in the death of hair metal and breaking the dam open for alternative music across the globe. So you must remember which year it actually came out...
