Bossa Nova.. as Jonathan said, the music is still around, but a short lived popularity from a dance perspective.
Most of the studios put together a " step " list of 10 variations, and yes, the basic is similar to samba, except, its danced in closed position ( like Kizomba ).It has strong similarities to the current club style of Bachata , which also uses a compact type of whisk .The Hip action is much more pronounced in B.Nova .
Most dances that are in closed position, are very intrusive for beginners ( B/room not so much )hence their survival rate is often short lived , or, go to an underground situation.
And, I dont know of any opportunities dance wise.
