I saw Ibrahim Ferrer a few years back before he died... one of the best concerts I've ever seen. The man could barely walk but he could still sing and work the crowd with a ferocity young punks can't match.
Most of the studio footage from BVSC the film is during the recording of the first follow-up record to the original BVSC album, which was Ibrahim Ferrer's solo record. After that disc sold well, they continued to do records with each of the featured musicians in the BVSC film... everyone of those albums is phenomenal.
