Lift Your Skinny Fists Like Antennas to Heaven, by Godspeed You Black Emperor! (2000): This was my introduction to "post rock," which doesn't seem like a very descriptive term to me. I'd file it generally under "progressive rock" in the original meaning of the term, not the stylistic label that's used mostly these days. Four long tracks (sprayed over two discs), all instrumental, with a few bits of spoken word or found vocal samples here and there. For the most part, the music develops languidly and is punctuated by some stark dynamic contrasts. I can't say it really sticks in my mind, but it's an intriguing enough of a listen.
