I've been trying to learn rift on drums but I can't figure it out. Any drummers on here that could give me some tips?

Fast and more cowbell.

1 2 3 4 1 2 3 4
CB --00--00--00--00--00--00--00--00
RC 0--0--0---0-0--00--0--0---0-0--0
KD 0--00--00--00--00--00--00--00--0

CB=Cowbell
RC=Rim Click
KD=Kick drum

The main Rift groove is actually a pretty simple Samba beat. The above clave pattern starts on the rim and then moves to the snare, I don't believe that it is absolutely correct, but it is something like this. The Cowbell pattern also moves to the ride for some parts, but pretty much stays the same pattern throughout.

I would just get comfortable playing the Kick on a-1, a-2, a-3 a-4, and the cowbell on and-a, and-a, and-a, and-a at the tempo of the song(120-130?) and then practice reading different clave parts with your left hand.

I just did some serious analyzation of this, I've been a drummer since 7th grade (I'm now a Sophomore in college) and I believe it's the same rhythmic pattern that Fishman does during the jam part of Foam and also in a small section of the composed part of Reba. I figured this by listening to the 5/8/93 version of Rift.

To see the beat I am talking about watch this video and listen to what Fishman does from 2:52 - 2:59 .

Can anybody confirm my take on this?

It's pretty simple. Just break it down, start slow and let your muscles learn what they're supposed to do. Just take it bar by bar. That's how I learned the drum part to Limb x Limb.

He's definitely doing more in Rift than in that small section of Reba, but I was just saying it's the same rhythmic pattern. They're both in four four, but the two patterns are very similar if you ask me. Not to mention sped up in Rift.
