Casino Rueda Salsa
Salsa - Casino Rueda 3 - Enio Cordoba's Latin Dance Team
In Casino Rueda a leader calls out dance moves which the circle then follows, including switches between partners.
Learning this style involves learning the different calls and knowing them whenever they might be called. For that reason, you may not want to try it until you have a bit of experience dancing and know some of the calls.
Google has a company Casino Rueda group that I have seen at Dance Spectrum in Campbell. I even got invited to join in one night and had fun doing that.
