I agree with Ian. There were some brilliant bands around in the early 90s, quite a few on the SubPop label; Buffalo Tom, Smashing Pumpkins, Pavement, Babes in Toyland, The Breeders, Belly, Sonic Youth, Mudhoney, Husker Du, Sugar and many others. Nirvana were just about the best of them with Pavement (try Slanted and Enchanted for their masterpiece) but I always had a soft spot for the talent and songwriting abilities of Buffalo Tom, the American equivalent of Teenage Fanclub, album after album of cracking songs.
I would not class the Pixies as part of this movement as they came slightly before and really inspired the whole thing. If you can listen to Doolittle and not end up humming about half of the tracks afterwards then I reckon you need a new set of eardrums.
