This video documentary by Ian Padron follows the legendary Cuban band Los Van Van on its 2006 national tour, during which founder, leader, and bassist Juan Formell passed the torch to his son, drummer Samuel. (Juan has continued to work with the band, though, and recently performed with it in Miami.) Band members past and present, musicologists, and noted composer Pablo Milanes discuss Los Van Van’s enduring power over nearly four decades, their interviews punctuated by stunning vintage performance footage. Starting in 1969, Formell radically modernized Cuban charanga with electric instruments and funky grooves, and over the decades the band has managed to adapt to changing tastes. But as the video makes plain, Los Van Van has long since become an institution, which has made such reinvention all the harder. 73 min.
