From this youTuber:
"Piazzolla Caldera" from the Oscar-nominated 1998 documentary "Paul Taylor: Dancemaker." The occasional voiceover is from Paul Taylor.
This piece will be performed in NYC on March 2nd and 8th, 2008 by PTDCo!
NY Times says "The genius of Paul Taylor lies in part in his seeming transparency. On the surface, Mr. Taylor's new 'Piazzolla Caldera,' ... is an exploration of the tango as a popular dance form, as cultural history and as music. Even more, however, 'Piazzolla Caldera,' set to music by Astor Piazzolla and Jerzy Peterburshsky, is a work whose complexities suggest why Mr. Taylor remains such a fresh and important artist after more than four decades."
