Rodolfo Biagi was a pianist, composer and director of the golden age of tango. He is known for his bold, rhythmical style of interpretation which takes the piano out of the background and into the spotlight. His nickname, Manos Brujas, means “sorcerer’s hands”. He is the author of many popular tangos such as “Indiferencia”, “Humillacion” and “Campo afuera”.
Rodolfo Biagi was born in Buenos Aires in 1906. Growing up in a humble family in the neighbourhood of San Telmo, it was difficult to convince his parents of buying him an instrument in his youth. However his insistence in becoming a musician was so strong they eventually agreed to buy him a violin and went to study at the conservatory of La Prensa.
Soon after he began his musical education Biagi discovered his preference for piano. He began working as a pianist at the Cine Colon when he was 13 years old and this is where Juan Maglio discovered him. He was invited to join the famous orquesta típica of Juan Maglio and began performing at the Cafe Nacional and Bar Dominguez on Avenida Corrientes. Later on he worked with the orchestra of Miguel Orlando at the Maipu Pigall, alternating with Elvino Vardaro, Cayetano Puglisi and Juan Bautista Guido. In 1930, he recorded with Carlos Gardel in the studios of Max Gluksmann.
After refusing an offer to travel to Spain with Carlos Gardel, Biagi joined the orchestra of Juan Bautista Guido and performed at the Cine Real and Cine Suipacha. There he missed the pleasure of performing im a cabaret and went back to the Pigall and Casanova with the orchestra of Juan Canaro.
In 1935, Biagi joined the orchestra of Juan d’Arienzo performing at the Chantecler. Together they worked for 4 years while forging their own styles until Biagi decided to assemble his own orchestra in 1939. This is when he began to fully express himself as a musician, taking his instrument another step beyond the simple role accompaniment which was usually reserved to the piano in tango orchestras.
Biagi made his debut as a director at the cabaret Marabu and Radio Belgrano. There he was remained 20 years and received the surname of Mano Brujas.
Rodolpho Biagi had a long successful career as a director. He worked with many signers including estribillistas Teofilo Ibanez and Andres Falgas in the beginning; Jorge Ortiz, Alberto Lago, Alberto Amor, Carlos Acuna and Carlos Saavedra later on in the 1940’s; Carlos Heredia, Carlos Almagro and Hugo Duval in the 1950’s and 1960’s. He appeared in the show Glostora tango club of Radio el Mundo and was the star of the television program entitled Casino Philips on Canal 13.
Rodolfo Biagi died on September 24, 1969 leaving 187 recordings as a director with the labels Odeon, Columbia and Music Hall. We can see him perform with the orchestra of Juan d’Arienzo in the 1937 movie “Melodias portenas”.
