In 1946 Piazzolla formed his Orquesta Típica, which, although having a similar formation to other tango orchestras of the day, gave him his first opportunity to experiment with his own approach to the orchestration and musical content of tango. That same year he composed "El Desbande", which he considered to be his first formal tango, and then began to compose musical scores for films, starting with "Con los mismos colores" in 1949 and "Bólidos de acero" in 1950, both films directed by Carlos Torres Ríos.
