This is a great half-time shuffle by Ash Soan, one of the excellent modern British drummers. One thing to note is that the shuffle on the hihat is "shank/tip" , the one of the triplet is played with the shank, and the three of the triplet with the tip. When you add the two of the triplet on the snare with the just right dynamic it sounds like a well played shaker, so it is important to get the mix right of the shank/tip/ghost to get that effect then you add the back beat and bass drum to complete it. And of course do all that at a slower tempo, then work it up to this tempo which is actually 6 BPM faster than Toto's Rosanna. If you want the details on the cool fill in the middle just contact me and I will show you what is happening.
