The Grammy winning bassist Israel "Cachao" Lopez died in Coral Gables, Florida, in March 2008, at almost 90 years of age. A maestro of legendary status on the world stage and ultimately considered one of the greatest Afro-Cuban musicians of all time, he had made his home in the United States for the past four decades. However, he continued playing the Havana clubs and dance halls with his brother Orestes. Together, they revolutionized the heart of Cuban music -- their spontaneous improvisations and innovations established the basis of, and the influence of, contemporary Latin jazz and salsa, rock 'n roll and rhythm and blues. The basis of this film is a sold-out 2005 concert at Bimbo's 365 Club, a famous San Francisco nightclub. Cachaos's life and work are palpable. "Cachao: Uno Mas" is produced and narrated by actor Andy Garcia, a friend and ardent fan, who helped reinvigorate Cachao's career in the 1990s -- and who appears in this film playing the bongos.
