Simple 4/4 triplet feel beat but with a syncopated measure of fill (pictured).  Snare and bass take turns on the triplet notes, while the cymbal is played on the down beats to keep the 4/4 beat true. Sounds really cool due to the syncopated snare and bass dancing around the real beat of the cymbal. It would sound like something you'd hear in a punk song if you played it with a normal quarter note feel instead (boom chicka boom chicka boom chicka boom chicka...)

Can't actually play it with the cymbal on the down beats yet. Playing one syncopated rhythm is hard enough! (Try just the cymbal and snare on a triplet beat for fun)

Also, I messed up and and added an extra beat during the second fill.
