I came across this very rare image of the great rumbero and composer Chano Pozo, with the famous jazz trumpeter Dizzy Gillespie.
Chano Pozo is playing a conga in the style used for carnaval/comparsa which is the origin of the conga drum and the term conga. The drum is known by the name conga because if it's historic relationship to carnaval/comparsa.
It's a great picture, Chano Pozo playing the drum and Dizzy Gillespie playing claves. Beautiful!
