modal harmonies and scales. In 1968 Piazzolla wrote and produced an "operita", María de Buenos Aires, that employed a larger ensemble including flute, percussion, multiple strings and three vocalists, and juxtaposed movements in Piazzolla's own style with several pastiche numbers ranging from waltz and hurdy-gurdy to a piano/narrator bar-room scena straight out of Casablanca. By the 1970s Piazzolla was living in Rome, managed by the Italian agent , and exploring a leaner, more fluid musical style drawing on more jazz influence, and with simpler, more continuous forms. Pieces that exemplify this new direction include Libertango and most of the , written in memory of Aníbal Troilo. In the 1980s Piazzolla was wealthy enough, for the first time, to become relatively autonomous artistically, and wrote some of his most ambitious multi-movement works. These included Tango Suite for the virtuoso guitar duo Sergio and Odair Assad; Histoire du Tango, where a flutist and guitarist tell the history of tango in four chunks of music styled at thirty-year intervals; and La Camorra, a suite in three ten-minute movements, inspired by the Neapolitan crime family and exploring symphonic concepts of large-scale form, thematic development, contrasts of texture and massive accumulations of ensemble sound. After making three albums in New York with the second quintet and producer Kip Hanrahan, two of which he described on separate occasions as "the greatest thing I've done", he disbanded the quintet, formed a sextet with an extra bandoneon, cello, bass, electric guitar, and piano, and wrote music for this ensemble that was even more adventurous harmonically and structurally than any of his previous works (Preludio y Fuga; Sex-tet). Had he not suffered an incapacitating stroke on the way to Notre Dame mass in 1990, it is likely that he would have continued to use his popularity as a performer of his own works to experiment in relative safety with even more audacious musical techniques, while possibly responding to the surging popularity of non-Western musics by finding ways to incorporate new styles into his own. In his musical professionalism and open-minded attitude to existing styles he held the mindset of an 18th-century composing performer such as Handel or Mozart, who were anxious to assimilate all national "flavors" of their day into their own compositions, and who always wrote with both first-hand performing experience and a sense of direct social relationship with their audiences. This may have resulted in a backlash
