There is a huge philosophical divide between mambo ( the forerunner ) and Salsa .
There are those who adamantly believe that they are 2 different dances .
There is an old Cuban saying " All salsa is Mambo.. but.. not ALL Mambo is Salsa " . That makes reference more towards the music, than the dance styles .
There is a World Champ. event in mambo held every yr in Miami.
Salsa has several contenders, primarily because it has no parent body. subsequently, there are at least 3 claimants to the title at any given moment .
There is a gradual return to the more traditional style of the genre ( I have 2 seperate teachers coming to me next week for training in mambo )
