Catúlo Castillo was a pianist, composer, director and poet of the guardia nueva. Son of a well-known playwrite and poet Jose Gonzalez Castillo, in his youth he distinguished himself mostly as 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 for political reasons.
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“.
Later in the 1920’s, Catúlo Castillo traveled Europe with his father and formed his own orchestra. From then on he would dedicate himself only to tango. As a composer he produced many pieces 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 socially engaged tango which was recorded by Carlos Gardel in 1925.
In the 1930’s and 40’s Catúlo Castillo became increasingly absorbed with poetry. With his friend Sebastian Piana and other composers he worked on remarkable pieces such as “Tinta roja” and “Caseron de tejas” (1941). In 1945 he began writing for Anibal Troilo with whom he produced his best work as a poet in the 1950’s.
The 50’s were critical years for tango as rock and roll was taking over the youth. Feeling perhaps that this was the end of an era, Catúlo Castillo took tango poetry to it’s last apogee. He wrote master pieces such as “El ultimo café” and “La ultima curda“, a deeply heart breaking tango where the bandoneon cries in 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.
