When one starts learning about tango, methodically getting to know what's what, one of the first things which becomes known is how influential was the work and musicians of Julio De Caro.
But it hasn't always been easy getting your hands on his recordings. So, he's well-known for being well-known - as opposed to beally really appreciated from hearing him.
A member of the Old Guard generation of 1910, Julio's work was so inspirational and revolutionary that he had much to do with setting things up for the Golden Age to happen.
Of course no other orquesta had violin as prominent as did Julio; and no other player amplified his sound with a horn like he did (violin corneta).
But the big deal about the De Caro orquesta was the 2 geniuses of the bandoneon: Pedro Laurenz and Pedro Maffia. These guys stunned everybody with where they took tango music. And after them, every bandoneon player was said to be in the style of either Laurenz or Maffia.
They play the most intricate voicings and runs as one.
