Montreal's Godspeed You! Black Emperor is not your average band. (Perhaps the group's name offers a clue to this fact, in which case, pardon me for pointing out the obvious.) Much more a musical collective than a band/brand hellbent on high-profile commercial success, GYBE, formed in 1994, might be considered the poster child for the "post-rock" movement, if we can even call it a movement. Dedicated to the construction of slowly evolving musical pastiches where layer upon layer of rhythmic and harmonic material builds toward a shuddering climax, the group is certainly not aiming its artistic intent toward the mainstream. But over the course of the past 18 years, GYBE has conjured a devout cult following, and it has certainly left a major mark on the still-burgeoning new-instrumental-rock stream, including the work of bands like Explosions in the Sky and Russian Circles.

On Tuesday, GYBE will release its first studio album in a decade, in the form of the intriguingly titled "Allelujah! Don't Bend! Ascend!"
