 His quartet was one of his most famous ensembles and he wrote many tangos.He was one of the few tangueros to play in a cafe in Avenida de Mayo in Buenos Aires and he was the first person to play the tango La Cumparsita in the cafe "La Giralda" in Montevideo, Uruguay.Firpo in 1930 gave up his tango career for a short while, to try his hand at cattle ranching, but he was forced to return to tango when the Paraná river's floods destroyed his livestock, and after that (trying to recover from the losses and trying his luck) he lost the rest of his fortune on the stock market.
