grunge is typified by an extended usage of alternative tunings
Hard rock, on the other hand, is typified by guitarits strongly influenced by blues...Typical hard rock bands would therefore be Led Zeppelin
Led Zep used more types of alternate tunings that the overwhelming majority of bands I'd say.
Perhpas grunge bands use more open tunings though.
Anyhoo, at least I can vaguely follow all this talk of differences between metal/rock/grunge/whathaveyou. Much easier than trying to work out what the fuck the difference is between "drum n bass", "garage", "techno" and the 5000000 different phat and flavour combinations that basically all just mean "house" to me.
EDIT: went back to the Going Out main forum page after making this post, and saw "electro bigbeat breaks" in the title of another thread. Enough said.
