how do i get into post-rock?
Go commit Goku or try mountain fraud
Godspeed You Black Emperor - Lift Your Skinny Fists Like Antennas To Heaven
And if you want more of the jangly, pretty stuff check out bands like Explosions In The Sky, This Will Destroy You and Sigur Ros and if you want more rock inspired, dirtier stuff then check out bands like Mogwai, Russian Circles and God Is An Astronaut
dont bother
