D'Arienzo contributed a fresh, juvenile, enlivening air to Tango.
Tango turned one day into a sad thought which can be danced to... It can be... The dance had become subsidiary then, but then had been displaced by lyrics and the singers, and now it is displaced by the arrangement.
So: D'Arienzo gave Tango back to the dancers' feet and with that he made Tango be again of interest for the young.
The King of Beat turned into the king of dancing, and by making people dance he earned a lot of money, which is a nice way to get it.
D'Arienzo made possible that Tango renaissance called La Década del Cuarenta (the 40s).
In 1949 D'Arienzo said: "In my point of view, tango is, above all, rhythm, nerve, strength and character. Early tango, that of the old stream (Guardia Vieja), had all that, and we must try not to ever lose it."
