R.I.P.
Duncan Reid told me Armando was the only Tjader alumnus that refused to be interviewed - he pretty much withdrew from the public after he stopped playing with Santana. The sessions released on the 10' LP Cal Tjader Plays Afroc-Cuban, reissued on Los Ritmos Calientes, were recorded under Peraza's name, but released as a Tjader album, much to his disapointment - Tjader had no influence on this. We corrected this in the discography by listing Peraza as a co-leader.
He was the top bongo player on the scene, along with Buyu (José Mangual, sr.) - with him, the great specialized bongo masters are all gone, I'm afraid. Hear him soloing on Big Noise From Winetka on the LP mentioned, on on Santana's Borboletta - unsurpassed.
