Godspeed You Black Emperor - The Dead Flag Blues (http://www.youtube.com/watch?v=-aLjup934Rk#)
Godspeed You! Black Emperor - Blaise Bailey Finnegan III [1 of 2] (http://www.youtube.com/watch?v=x_kCruB92PU#)
some songs from their side band, A Silver Mt. Zion:
A Silver Mt. Zion - Sit in the Middle of Three Galloping Dogs (http://www.youtube.com/watch?v=T_Mot5iGloY#)
ASMZ - 13 Angels Standing Guard 'Round the Side of Your Bed (http://www.youtube.com/watch?v=hQZfGa5t4e8#)
(in a couple of songs these guys use bits of Christian preacher sermons, but they are not Christian themselves... they are more like far-leftist anarchist types)
