Agustín Magaldi Coviello was an Argentine tango and milonga singer. His nickname was "La voz sentimental de Buenos Aires". Magaldi took part in the opening broadcasts of Argentina's LOY Radio Nacional in July 1924.
Magaldi suffered from liver disease and was admitted to Sanatorium Otamendi early in September 1938. An operation by Dr. Pedro Valdez was successful, but Magaldi died 48 hours later. He was buried in La Chacarita Cemetery in Buenos Aires.
