OK, maybe I'm not crazy. I have seen that same rhythm written before, but I have also seen some much more complex patterns listed as "rumba". You're confirmation is what I was hoping for.
so if it is a Rumba, then......
What I have found frustrating in the past, I ask the drummer for a rumba, and what I get is a very busy rumba beat that sounds more Latin than rock or blues.
It's a rockin' rhumba, and the snare is still on the 2 and the 4 on your example and there's ornamentations being done mainly with the with the cymbols and sometimes on the floor tom. There are actually many different rhumba grooves including rhumba grooves that have a distinctive swing feel to them, especially when the guitar player, for rhythm playing are using 6th chords. Heck, even Albert King's earliest version of Crosscut Saw is also a rhumba groove as well and it is a very distinctly different sounding groove and below is his version of a rhumba groove on his classic LP Born Under A Bad Sign backed by Booker T & The MG's.
Obviously, there's many different ways to play a rhumba groove. ---------- Sincerely, Barbeque Bob Maglinte Boston, MA http://www.barbequebob.com CD available at http://www.cdbaby.com/cd/bbmaglinte
