The later age of tango has been dominated by Ástor Piazzolla, whose "Adiós nonino" became the most influential work of tango music since Carlos Gardel's "El día que me quieras" was released in 1935. During the 1950s, Piazzolla consciously tried to create a more academic form with new sounds breaking the classic forms of tango, drawing the derision of purists and old-time performers. The 1970s saw Buenos Aires developing a fusion of jazz and tango. Litto Nebbia and Siglo XX were especially popular within this movement. In the 1970s and 1980s, the vocal octet Buenos Aires 8 recorded classic tangos in elaborate arrangements, with complex harmonies and jazz influence, and also recorded an album with compositions by Piazzolla.
