I found this music surprisingly interesting. You see, I was set up with impression before even hearing them because of this group's connection to Godspeed You! Black Emperor (most concretely through this bands founding by Roger Tellier-Craig). Indeed they do belong in the same web of artists and bands that have exploded around the legendary Montreal post-rock collective, yet these guys are both the same and different. While certainly possessing the long, epic build of GY!BE, they're considerably more psychedelic in sound. A notable variation from some of the other Montreal post-rock acts associated with these guys is the liberal use of vocals, but not necessarily lyrics. Rather the voices are rhythmic repetition of sounds and shouts that add remarkable energy to the tracks. Overall, I'd say if you like experimental rock at all from the mellow post-rock to high-energy noise you should find something you like about Et Sans.
