Seven years after the fact, but THANKS! for the explanation to the guy that asked about the intro; I was struggling with that too. Thanks for your track.
Start the d/e "Hammer Frill" almost immediately, listen to the ride cymbal it will become steady beginning with a stronger hit (0:17-0:18) sync that first E note for the main riff with this beat. The main riff is played twice with a walk down at the end of the second time ending with the Snare hit I know your like What?
