Cafe Cantante Mi Habana, Havana
This place is a must if U wanna enjoy good live music. It has various groups, each day something different. From tipycal cuban salsa, latin jazz, pop and rap. Every saturday from 4-7 pm (matinee) and from 10pm to 3am. In the matinee is more usual to find there young cubans looking for fun, is a good opportunity to get to know the locals.
I recomend on thursdays, the group Sintesis. Very well known worldwide because of their special blen of jazz, rock and afro cuban rithms. They have played in pretigious jazz clubs around the globe and even in the very well known Rock in Rio with rock stars like Sting, Red Hoy Chilli Peppers, Sepultura and others.
