Can anyone tell me what this crazy Brazilian dance called axé is all about?

Answer 1

Samba Axé is a solo dance that started in 1992 during the Brazilian Carnival season in Bahia when the Axé rhythm replaced the Lambada.
For years it became the major type of dance for the North east of Brazil during the holiday months. The dance is completely choreographed and the movements tend to mimic the lyrics.
It's a very energetic kind of dance that mixes elements of Samba no pé and aerobics and because of the lyrics, which are made for entertainment, the dance generally has some sort ludic element.

Several Axé music groups such as "É o Tchan" have as part of their marketing strategy to always release a choreography together with every one of their songs; therefore,
Samba Axé is an ever-changing kind of dance with no commitment to maintaining any formal set of steps or routines (there's actually no such a thing as a basic step in Samba Axé.)
