Aníbal Carmelo Troilo (July 11, 1914 – May 18, 1975 in Buenos Aires) was an Argentine tango musician.

Anibal Troilo was a bandoneon player, composer, arranger and bandleader in Argentina. His orquesta típica was among the most popular with social dancers during the golden age of tango (1940-1955), but he changed to a concert sound by the late 1950s. Troilo's orchestra is best known for its instrumentals and also recorded with many vocalists, such as Francisco Fiorentino, Alberto Marino, Floreal Ruiz, Roberto Goyeneche, Raul Beron, and Edmundo Rivero. The rhythmic instrumentals and the recordings with vocalist Francisco Fiorentino from 1940-41 are the favorite recordings for social dancing in contemporary tango salons (milongas). The renowned bandoneonist Astor Piazzolla played in and arranged for his orquesta típica during the period 1939-1944.

Troilo's own tango compositions include:

Carlos Ignacio Carrillo Contreras (November 5, 1940–March 4, 1994) was a Mexican Luchador, or professional wrestler known under the ring name Aníbal. Carrillo made his debut in November, 1963, but it would not be until 1965 where he adopted the enmascarado character (masked) Aníbal, named after the Carthagenian general Hanibal. Carrilo's career peaked in the late 1960s and the 1970s as he worked for Empresa Mexicana de Lucha Libre and the Universal Wrestling Association, winning a number of championships. Carrillo was unmasked after losing a Lucha de Apuesta (bet fight) to Máscara Año 2000 on December 13, 1991. Carrillo retired from wrestling in 1993 and died from a brain tumor in 1994. El Hijo de Aníbal (Spanish for "the Son of Aníbal") is billed as Aníbal's son, but it has never been confirmed if he is indeed the son of Carrillo or if he paid for the rights to use the name, a practice not uncommon in Lucha Libre.

Leonel Edmundo Rivero (June 8, 1911 – January 18, 1986) was an Argentine tango singer, composer, and impresario.

Rivero was born in the southern Buenos Aires suburb of Valentín Alsina. Joining his father in some of his travels, he was exposed to the lifestyle and the music of the gauchos of Buenos Aires Province from his early days. His maternal great-grandfather, named Lionel, was a British immigrant, and fought against the Pampas tribes in the mid-19th century, being wounded by a spear. From him, Rivero inherited his blond hair and his first name.

In his teens, Rivero's family moved to the Belgrano neighborhood, in the days where tango developed as a dancing phenomenon, but also as an ever more complex music form under the "ABC" of composers/directors Arolas, Bardi, and Cobián. At the same time, the themes of tango lyrics evolved from light-hearted ribaldry into more complex stories delving on love and manly honor.

Rivero learned classic guitar and also trained as a singer; he had a deep bass-baritone voice that was one of his trademarks, together with his huge hands (due to his acromegaly) that made him the butt of many jokes.

Roberto Goyeneche (Saavedra, Buenos Aires, January 29, 1926 – Buenos Aires, August 27, 1994) was an Argentine tango singer of Basque descent, who epitomized the archetype of 1950s Buenos Aires' bohemian life, and became a living legend in the local music scene.

He was known as El Polaco ("the Pole") due to his blond hair, and thinness, like the Polish immigrants of the time. He is identified with the neighborhood of Saavedra, where he grew up.

Roberto Goyeneche was formed in the style of the tango of Carlos Gardel, later reached a more personal style. In 1944, at the age of 18, he joined Raúl Kaplún's orchestra after winning a local contest and soon gave his live debut performance on Radio Belgrano. In 1952 Goyeneche teamed up with Horacio Salgán.

In 1956, he became the singer in the orchestra of his dear friend Aníbal Troilo, with whom he recorded 26 songs. Later, Goyeneche became the first singer to record Ástor Piazzolla's classic Balada Para Un Loco, after starting his solo career in 1963.
