Didn't want to type 'Grunge' as it's a term that has always frustrated me - but, yeah I guess that's what I mean. Doesn't have to be on those three labels but you get my drift. Nirvana allowed Pearl Jam too if you really have to.

For it's timing, cover and setting the scene up to an extent I'm going with Mudhoney - Superfuzz Bigmuff. Glorious record (technically an E.P, but hey)...
