This is a Latin dance and is a mix of different Cuban dances. There are many different regional versions of the Salsa, most of which are North American.
In Salsa, weight shifts are done in the hips with arm and shoulder movements incorporated.
With the New York style, the dancers remain in front of each other while in the Cuban style they circle around each other.
Performed on the night by Marcus and Maria to “Mas Que Nada” by Sergio Mendes and Black-Eyed Peas
