Catúlo Castillo was a pianist, composer, director and poet of the guardia nueva. Son of Jose Gonzalez Castillo, in his youth he distinguished himself a musician and composer. After the death of his friend Homero Manzi in the 1950’s, he revealed himself as the last great poet of the golden age.
Ovidio Catúlo Gonzalez Castillo was born in Buenos Aires in 1906. He grew up in Chile where his father José Gonzalez Castillo exiled himself until 1913 because of his political ideas.
Back in Buenos Aires, the family moved to Boedo where Catúlo began learning the violin with Juan Cianciarullo. By age 17 he was an accomplished musician and boxer. He won the national championship of lightweight in Argentina and almost reached the Olympic games of 1924. That same year he won the third place in a contest organized by Max Glucksmann with his tango “Organito de la tarde“.
During the 1920’s, Catúlo Castillo definitely turned to tango as he traveled Europe with his father and later with his own orchestra. As a composer he produced many tangos including “Organito de la tarde”, “Silbando”, “El Aguacero”, “Papel picado” and “El circo se va” with the lyrics of his father Jose Gonzalez Catillo, “La violeta” (1930) with Nicolás Olivari and “Viejo ciego” (1926) with his friends Sebastian Piana and Homero Manzi. He is the author of both music and lyrics of “Caminito del taller” (way to the shop), a politically engaged tango which was recorded by Carlos Gardel in 1925.
In the 1930’s and 40’s Catúlo Castillo became increasingly engaged with poetry. With his friend Sebastian Piana and other composers he wrote remarkable pieces such as “Tinta roja” and “Caseron de tejas” (1941). In 1945 he began working with Anibal Troilo with whom he produced his best work as a poet in the 1950’s.
The 1950’s were critical years for tango as rock and roll was taking over in popularity with the youth. The great poets of the golden age were gone or had diminished their activities and it became increasingly difficult for tango orchestras to get work. Feeling perhaps that tango was coming to an end and building on the work of every other authors who came before him from Evaristo Carriego to Enrique Discepolo, Catúlo Castillo took tango poetry to it’s last apogee with titles such as “El ultimo café” and “La ultima curda” where the bandoneon cries in to the lonely man’s imagination “life is an absurd wound”.
Other tangos of that period by Catúlo Castillo include “Domani”, “La calesita”, “El cafe de los Angelitos” and “El patio de la Morocha”.
Besides his activities as a lyricist, Catúlo Castillo had an active professional life. In the 1950’s he became President of the SAIDAC and president of the Comisión Nacional de Cultura . He was declared Ciudadano Illustre of the City of Buenos Aires in 1974 and died the following year at age 69.
