Play the top one, and about one second in, play the bottom one. Perfect sync will lead to extremely violent eargasms
This. To clarify, play the first one, then at the second beat play the second one. May take you a few tries, but you'll get it eventually. You don't have to get it down to the millisecond, a very very slight delay between the drums adds some nice "impact" to the sound, for want of a better word.
