In March of 1953 Villa-Lobos was in Barcelona for the Festival de Musica Sudamericana, to promote his own music (he never stopped doing that), and the music of a number of his colleagues from Latin America. Here is his program; Villa conducted the Orquesta Sinfonica del Gran Teatro del Liceo, with pianist Ramon Castillo.
This is some real leadership by Villa-Lobos. He's using his by then considerable fame to help boost the careers of friends in South America. The first piece he chose was a premiere of a work written in 1920: La Voz de las Calles by the Chilean Pedro Humberto Allende. Allende is an almost exact contemporary of Villa-Lobos; he was born in 1885, two years before Villa, and died the same year, 1959.
I wasn't able to track down a performance online of the Obertura Criolla by the Argentine Ernesto Drangosch (1882-1925). His piano music seems to be quite popular, though.
Villa-Lobos often included his friend Oscar Lorenzo Fernández in programs he conducted. Imbapára is an impressive Indianist work from 1928.
Evencio Castellanos (1915-1984) is an important Venezuelan composer who deserves to be much better known. El rio de las siete estrellas is a fine work; I praised this version by Jan Wagner and the Orquesta Sinfonica de Venezuela back in 2012.
When you add these four works to the Momoprecoce and especially Choros no. 6 by Villa-Lobos, this is an impressive evening of music!
