This was a masters class seminar at La ENA in Havana Cuba. It features:
Changuito - Percussion
Carlos Del Puerto - Bass
Pupy Pedroso - Piano
It is long, and no there is no video, this is the audio, but for anyone interested in Cuban music, this is pure gold.
I believe it was Carolina Sanchez translating, so it is in both English and Spanish.
This was in 1995, I think April, but I don't remember.
