Post-Metal/Rock?

Is it bad that I can get into shit like Pelican and Isis, but I can't get into Neurosis?
Pot helps.

Seriously though (at least, if you don't smoke), Neurosis are kind of hit and miss with their songs but when they're on, they're on like a motherfucker! Their hits:
No River to Take Me Home
Watchfire
A Season in the Sky
Through Silver in Blood (at least the first half)
Locust Star
Under the Surface
Raze the Stray
Aeon

If you haven't heard these songs, check em out - especially if you're in that Floydian frame of mind.
