Expansive Chord Progressions

IV → I → V → vi

The expansive, building progression of post-rock. A-E-B-C#m creates slow-building emotional crescendos. Layers of delay, tremolo picking, and dynamics define Explosions in the Sky's signature sound.

I → V → vi → IV

The endless loop that defined atmospheric arena rock. D-A-Bm-G repeats unchanged throughout the entire song, creating an open-ended mood. The Edge's delay-drenched guitar makes this simple progression sound infinite.
