The Argentine Republic proclaimed the "National Day of Bandoneon" on July 11th, the birthday of Anibal Troilo. This day was established through Law 26035, which was enacted on May 18, 2005. Troilo was a renowned Argentine tango musician and bandoneon player who fell in love with the bandoneon as a child and played it for his entire career. He composed many famous tangos, including "Sur" and "Responso," and was known for his generous nature and ability to lose himself in the music during performances.
