Osvaldo Pedro Pugliese was an Argentinian tango musician. He developed dramatic arrangements that retained strong elements of the walking beat of salon tango but also heralded the development of concert-style tango music. Some of his music, mostly since the 1950s, is used for theatrical dance performances. In Buenos Aires, Pugliese is often played later in the evening when the dancers want to dance more slowly, impressionistically and intimately.
