Eduardo Arolas, also known as El tigre del bandoneon, was an influential bandoneon player, composer and director of the early days of the guardia vieja. He is the author of over 100 tangos including classics such as “Derecho viejo”, “La cachila”, “Retintin” and “Comme il faut”. With his vanguardist compositions and quality of interpretation, he contributed largely to define tango in its early stage. Many distinguished musicians of the guardia vieja made their debuts in his orchestra including Juan Carlos Cobian, Julio de Caro and Luis Bernstein.
Lorenzo Arola was born in Buenos Aires in 1892. He grew up in the neighbourhood of Barracas where his father owned a store. With his older brother he learned to play the guitar when he was 8 years old and began playing in the cafes of la Boca. This is how he met Ricardo Gonzalez who first thought him to play the bandoneon. Together they performed in duo for a while until Eduardo went his own way.
In 1911, Eduardo Arolas was 19 years old and fully dedicated to music. He studied with Jose Bombig and opened a café called “Una noche de garufa” where he performed on his own. This is where he composed his first tango, which bears the same name as the cafe.
Like many tango musicians of the first generation, Eduardo Arolas didn’t know how to read or write music. However he was a brilliant, prolific and innovative composer. He was also known for his style of interpretation and phrasing, which is more fluid then other orchestras of that time and sets new standards for tango musicians.
With his talent as a composer and interpreter, Eduardo Arolas quickly became popular around the city. With Leopoldo Thompson (guitarra) and Ernesto Ponzio (violin), he began performing at Café La Turca and traveled to Montevideo. Back in Buenos Aires, he formed another trio with Agustín Bardi (piano) and Tito Roccatagliatta (violin) and later on a cuarteto with flute. He was invited to perform at the prestigious cabaret Armenonville with Roberto Firpo in 1913 and then began forming his own orchestra.
With his orquestra típica, Eduardo Arolas continued performing in prestigious venues and cabarets such as El Estribo, L’Abbaye and Montmartre. He performed at Café Botafogo and Royal Pigall in In 1916 and Café Apolo in 1917. In those years he composed some of his most famous pieces and left recordings in which we can hear him play solo or with his orchestra.
During the last years of his life, Eduardo Arolas suffered from depression and alcoholism. He traveled extensively to Montevideo where he was a star at the carnavals of 1920 and to Paris where he performed at prestigious venues such as the Cabaret Parisien and Ermitage, contributing to the popularization of tango in the old world. He died in Paris in 1924 at 32 years old.
