From Wikipedia re Colombian Style Salsa (Vive Colombia!)

Colombian Style Salsa is the style danced in South and Central America. In the Colombian style basic-step, partners dance side-to-side and mirror each other’s movements. In Colombian style, the break is on the three and the "spare beat" is always used for a tap or other embellishment.

Colombian Style can be danced not only to Salsa music, but also to Cumbia music which is frequently played in Latin nightclubs.

In advanced Colombian style, danced for example in Cali, the upper body is kept still, poised, and relaxed while executing endless intricacies in the feet.

This style is especially appropriate on packed nightclub dance floors where space is limited. Most of the steps danced during the Merengue , another Latin dance which is popular in Salsa clubs, have been carried over from Colombian style Salsa.

It is said that Colombian salsa evolved during the big band swing era, when swing dance steps were danced to Cumbia music. Cumbia was traditionally danced in folkloric ensembles without holding one’s partner.
