The Medal test will eventually come to pass ( just like Disco )
As to the book..have not read or seen it.
I was recently asked on another site ,about my feelings on the B/room worlds entry into the salsa genre , and questioned why I was not conversant with ALL the syllabi of my english Soc. to which I belong.
Simply put.. the syl. I use, is the very foundation of ALL standardised teaching ( in Mambo/Salsa) going back to the 40s ;the basics have never changed, and most of the advanced variations are still being used. The techniques have been honed to some degree, but nothing radical.
The other main consideration, is the lack of long time practical knowledge ( like dancing in latin clubs for many yrs ), that exists within the Soc.
If one is trained in the Intern. style of "Latin ", there is a tendency to retain the ballroom "look".. I know.. I went thru that phase, which took me yrs to rethink the more indigenous concepts of the "street" style approach.
You know what they say about learning a language.. go live in the country and mix with the " natives "...
