I'm not trying to play it or anything, but this song arrangements have been bothering me since the first time I heard it, and I can't seem to get what's going on in a part that repeats several times throughout the piece. It starts at 01:12.

The whole song is awesome, by the way. Nice production and composition. Listen to it all the way through even if you don't know what's going on either.

4/4. It's just accented weird.
Only play what you hear. If you don’t hear anything, don’t play anything.

4/4 its where the drummer doesn't accent the 1 but the 4 and, i think, love grizzly bear tho man, great new band.
