Can I add to the pattern? :)
Freaking great groove once it gets started. Awesome and potential for more development! But like a waiter who tells you their life story before getting to the specials or taking your order, the intro tremolo guitar fest just eventually glazes one's eyes over, or mine at least.
Adding to the kabosh is the tremolo not being 100% in sync with the bpm. The longer the tremolo delay sustains, the less it's in time. I understand that can be used as a cool effect, so that might be your approach here.
You clearly know how to tremolo and there's plenty of it in your tune elsewhere, and it really adds to the vibe of course.
I really really liked it when the grooves kicked in!!!! Down and dirty it was! Well done!
I'd only add it took me a while to write the above, so I got to listen to more of your tunes on Soundclick, you've got some good ones up! Nice going and good writing/mixing!
cheers,
