One of my favorite post-rock bands. They have been around for over ten years now and they are still releasing great music. Each album is a little different in the style that they go for. Some are more rock and others more ambient. They have not gotten the same amount of media attention that Explosions In The Sky has but I'm pretty sure that they are due. So be on the lookout for these songs in commercials and movies.
And the founder Johnathon Ford was the bass player in Pedro The Lion for a while. In case that convinces someone to listen.
