This time around it's former Hermeto Pacoal and current Hamilton de Holanda drummer, Marcio Bahia, who I've written about before. Along with bassist Eduardo Machado, and pianist Gil Reis, the trio released an album last year called simply, "Em Tres".
There are two similar grooves here, mainly differentiated by what's going on in the right hand.
The groove itself is in 9/8 or 3/4, and feels pretty much like your standard Bembé minus one beat. Bahia plays the Bembé pattern pretty much by the book on the ride cymbal throughout the first section. But in the second bar, much like Kiko Freitas does on "Vento Bravo", he then shifts the bass drum to the third 8th note of beat 1.
I don't have a link that I can post, but the album is on Spotify if that's you're thing.
