The Cuban vocal quartet Los Zafiros (the Sapphires) reached the height of their popularity in the 60s, when their fusion of calypso rhythms, doo-wop harmonizing, and Motown choreography won the adoration of native and European fans alike. In this sleek, nostalgic, sensibly structured documentary (2002), filmmaker Lorenzo DeStefano strolls down memory lane with the two surviving members, guitar accompanist Manuel Galban and singer Miguel Cancio (the latter now enjoying a comeback as part of the Buena Vista Social Club), as well as family members and longtime associates in Miami and Havana. The songs, exuberant or sad, speak for themselves, none of them more poignant than the one Cancio croons for Galban in a studio session, paying tribute to their time together. In Spanish with subtitles. 87 min.
