Candombe and Canyengue, why forget them?

Several time we were in disputing the execution or not of the old origin of Tango called Candombe, during an exibition in public. We are formally convincted about the necessity, in all those training professional or near professional, of dancing Candombe and Canyengue, to permit to dancers the fully understanding of the mechanism which evolved onto Argentine Tango and Tango Nuevo since the beginning of its history.
