Check out this clip - Cachao and pianist Bebo Valdes (who long ago defected from Cuba and moved to Sweden) playing together for the first time in many years, from the great documentary/concert film "Calle 54" (a must for fans of Latin and Brazilian styles).

And I'll name drop here: I had the privilege of briefly speaking to Cachao in Miami, when "Calle 54" premiered at the Miami Film Festival, and I got to observe at an afternoon rehearsal and evening concert by Cachao, Bebo and percussionist Carlos "Patato" Valdes. Unforgettable. Cachao's rhythmic feel and big tone were amazing - one of those players who was simply irreplaceable.
