There seems to be a ton of bands out there, whose names I have heard over and over, and even though I have never heard their music (and probably won't) I can just TELL what they sound like. Does anyone else have these?
some examples:
Okkervil River - sounds like Going Up The Country by Canned Heat (thx. Hippie Johnny for searing that tune into my head) but with prominent banjo playing.
Gogol Bordello - Circus/ Calliope music with "tribal"-style drumming. Lots of weird tinky sounds like triangles and toy pianos.
The Bevis Frond - If a band could make entire albums based around that sound when the bass player slides from the high note to a real low note in one smooth "brrrrrrrooooooooooowwwnnnnphh", it would be this band.
