Melvis Santa is an Afro-Cuban jazz vocalist, pianist, percussionist, and actress that has been wowing crowds at the biggest theaters in Havana since age seven. At 14, Santa put together a vocal ensemble that the great Chucho Valdés called “the best Cuban vocal quartet of the past 30 years.” She comes to Cafe Erzulie for a Soundoff Sessions performance with the JGI. Sets at 8 and 9:30, Soundoff Sessions until late. Creatives, bring your axe — whatever it is — and your energy.
