I'm a pretty big fan of Godspeed You! Black Emperor, Set Fire To Flames (which has some members of Godspeed...), Mogwai, and Sigur Ros.
I'm also in a small post-rock band myself. We don't have any recordings yet, so don't ask me for them. My brother's in fairly big post-rock band in Duluth, Minnesota. If you feel like it, their myspace site is
