An operatic tenor who broke the color barrier in one of Cuba's most prestigious orchestras, and a musical ambassador to the United States and Europe, Antonio Machín was a pivotal figure in the history of Cuban music who is not always remembered as such. While perhaps the greatest sonero of the pre-war era, his recorded output from this period is frustratingly uneven. Several discs document Machín's career between 1929 and 1938, a prolific period when the superb quality of his best performances was not often equaled. Machin was also by nature an itinerant soul, which may account for his relative obscurity today. He left Havana for New York in 1930, New York for London and Paris in 1935, and finally Paris for Madrid just before World War II, where he lived until his death in 1977.
