Astor Piazzolla, brilliant, iconoclastic tango musician and composer, has become a national hero in Argentina and a cult figure for classical and jazz lovers worldwide, but only after a lifetime of controversy and struggle.The outspoken, headstrong Piazzolla told his story to journalist and longtime fan Natalio Gorin in the spring of 1990 in a series of frank interviews.Among the firsthand observations of others who knew Piazzolla well are those of his lyricist Horacio Ferrer, his fellow musicians, and his colleagues. Translator Fernando Gonzalez, an Argentine native and American popular music critic who covered Piazzolla's career in the United States, has annotated the Amadeus edition for the widening audience that is rediscovering Astor Piazzolla.
