Rodolfo Biagi was a pianist, composer and director of the golden age. He is particularly 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 also 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 the neighbourhood of San Telmo, in a humble family where he was the first musician, he had difficulty convincing his parents to buy him an instrument. However his conviction was so strong and he insisted so much that they agreed to buy him a violin.
While studying at the conservatory of La Prensa, Biagi discovered his preference for the piano. He began working as a pianist at the Cine Colon when he was 13 years old. This is where Juan Maglio discovered him and asked him to join his famous orquesta típica. Together they performed at the Cafe Nacional for two years before they moved on to Bar Dominguez on Avenida Corrientes. Then 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 for a more engaged public so he went back to the Pigall and Casanova with the orchestra of Juan Canaro.
In 1935, Biagi joined the orchestra of Juan d’Arienzo who was performing at the cabaret Chantecler. Together they worked for 4 years and began forging their own unique styles until Biagi went on to form his own orchestra in 1939 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 orquestas tipicas.
Biagi made his debut as a director at the cabaret Marabu and Radio Belgrano where he was remained for 20 years and received his surname of Mano Brujas. Singers he worked with at the beginning of his career as a director are Teofilo Ibanez and Andres Falgas. In the 40s he worked with Jorge Ortiz, Alberto Lago, Alberto Amor, Carlos Acuna and Carlos Saavedra. Finally, in the 1950’s and 60’s, he worked with Carlos Heredia, Carlos Almagro and Hugo Duval. He appeared in the show Glostora tango club of Radio el Mundo and became the star of the television program 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. He can be seen performing with the orchestra of Juan d’Arienzo in the 1937 movie “Melodias portenas”.
