From the New York Times obit:
Francisco Aguabella, a Cuban-born master percussionist whose impeccable rhythmic sense and drive enriched the recordings and live performances of jazz, salsa and pop artists for five decades, died on May 7at his home in Los Angeles. He was 84.
The cause was cancer, said his daughter Menina Givens.
Mr. Aguabella’s main instrument was the conga drum, on which he showed remarkable versatility. Of the scores of recordings on which he played, Paul Simon’s 1990 album “The Rhythm of the Saints” is probably the most celebrated. But he proved to be equally comfortable playing with Frank Sinatra at Caesars Palace or with the Dizzy Gillespie and Machito band at jazz festivals.
