The Grand Finale, of which La Cumparsita is the most impressive, of the 80 minutes of fireworks in La Boca.
Note the white fireworks, which mimic the move of a bandoneon...
The last half of the video shows 'tango nuevo', the latest re-incarnation of tango by a younger generation, who likes to dance 'apart' instead in a 'close embrace', using many figurative steps, and unconventional tango music. Personally, I prefer traditional tango salon - but, tastes differ of course.
This last segment of the show, represented the history of tango, starting with newly arrived immigrant men dancing with men (about 100 years ago or a little more) via classic tango of the Gardel years, to jazz inspired tango by Piazolla to Tango Nuevo often accompanied by electronic music.
Anyway - this is what over 250,000 spectators came to see - or not to see - depending on their location among the tightly packed crowd. Only privileged 'invitados' and television crews enjoyed a close-up of the fireworks and dance as in this video, and only 'the front ranks' could see the floating fire fountains on the river.
Spectacular indeed!
