The first song was I N S A N E!! I wasn't so sure about the rhythmic ostinato on which the second is built unfortunately. Third one is really good, the keyboard motif reminded me of undertale a little. Fourth one, I liked the spicier harmonies. Fifth one, was the one I liked the most after the first one, the drums felt really nice on that one. If you don't have yet, make a post-rock album the world will thank you for it (or at least I will lol).
