As someone who enjoys post-rock music and other music that involves lots of repetition and buildups, I very much enjoyed your submission.
The use of the guitar slightly in the background with all of the textural change in the foreground was super cool and quite appropriate for the atmosphere you were creating, as well as the themes of this jam.
Honestly the only real feedback I have is that I would've liked to have heard just a little bit of change in the guitar near the end of the piece, where the instrument becomes a little more exposed along with the percussion. Even if it was just altering the chords/voice leading by a note or two. I think it could've been a nice complimentary section that adds a little bit of variation to give the listener something different to hear for the outro.
Thanks for sharing this! Keep up the good work :)
