Don't make any mistake, each of the four instruments (drum + cymbal considered as a single drum kit) is trying to tell you something.
The (non bass) guitar is probably the easiest one to interpret.
is the guitar's score. What happens per bar if you interpret the rests as zeroes and the notes as ones? This should lead you to the other instruments,
if you ignore bar 17. Some might say such an oversight is dotty, or doesn't feel right, but that's all Greek to me... it's just the preferred artistic version!
