self-righteous, but never right
Still, 1991 was a bloody great year (especially for me in my early 20s). I've not seen the BBC programme yet, however the Sonic Youth documentary '1991 - The Year Punk Broke' is definitely worth a watch for anyone who hasn't seen it.
1991 was a great year for music. Here's Spin's to 20 (a bit confusing as it counts down from 20 to 1, but the labels go from 2 to 21).

Number 1 may surprise you. Not that it isn't a great album, but that it's #1.
I lived in Seattle between Bleech and Nevermind (89-91). Mudhoney was king. There many good to great non-grunge bands too. Posies and Young Fresh Fellows, for example.
