The Kennedy Center website has the MB SB listed on the ballet web page and also on the contemporary web page, while a company like Alvin Ailey is only listed on the contemporary web page.
My friend went to their master class yesterday and learned some of the choreo from the final ensemble dance. He said it was like "Lots of theatrical attitude, plus a little jazz, a little Travolta...and a hint of the Pony." I was hoping to also take the class but was busy with our local Nutcracker. I will see the performance later today.
