A tango opera by Ástor Piazzolla. The ill-omened María, born "one day when God was drunk" in a poor suburb of Buenos Aires, heads to the center of Buenos Aires, where she is seduced by the music of the tango and becomes a sex worker. Thieves and brothel keepers, gathered at a black mass, resolve her death. First performed on 8 May 1968 in Buenos Aires, Argentina. Recorded theatre performance.
