Of the twelve concerti that make up Vivaldi's L'estro Armonico, Op. 3, the Concerto for Two Violins in a minor, RV 522 is one of the few that retain their popularity today. Along with J.S. Bach's own double concerto, it may be one of the most beloved works for two violins ever written. This edition for two violins and piano is edited by Ivan Galamian and Giuseppe Piccioli.
