Absolutely bangin' tune!
Badassness all over those drums and bass synth, man!! Rock!! There's something about one of the whistel-y pads that seems off-key to me...
I'm a fan of cut-n-bash back to the beats too... hehe! You did it proerper, I think, with that bass drawn out... maybe add a second rise-in as the sample revs back to the beat?? Or, completely add a delay to the sample, then wait for a pause then SMASH, in comes the beat?? Just a couple thoughts...
This is definitely tight, bro!
Peace always!
