Astor Piazzolla was a bandoneon player and a composer in Argentina who lived during the 20th century. He changed both classical music and tango music by bringing the two together. The Neave Trio, who recently came out with an album of Piazzolla's work, teaches all about who he was and how his genre-hopping changed music.  Music list:   Special thanks to Todd Reynolds for his music, Taskforce: Farmlab from Outerbourough.
