I saw and reviewed this several years ago...you are right, the music is great.

from The Boston Phoenix...

Leon Ichaso's occasionally melodramatic but always engaging love story is set amid the socio-economic wasteland that is modern-day Havana. Gustavo (One Life To Live's Rene Lavan) and Yolanda (The Specialist's Mayte Vilan) meet in a nightclub and fall instantly for each other. Gustavo is a young engineer who has been promised a scholarship to study in Prague; he's loyal to the Castro regime. Yolanda, a dancer, hates the Communists and wants only to escape her poverty. Complicating matters, Gustavo's brother Bobby is a young Cuban "rockero" who, like his friends, injects himself with the AIDS virus to protest the political system. And their father, a once-prominent psychiatrist, is reduced to playing piano for tips in a hotel bar. Physical passion and hope for the future obfuscate the lovers' differences at first, but eventually Yolanda departs for Miami, leaving Gustavo to accept that his trip to Prague will never come about. Based in reality but photographed in dreamlike monochrome, Bitter Sugar offers a powerful glimpse into a country poisoned by soured dreams of a revolution that may never occur.
