The Waking Life OST was performed and written by Glover Gill and the Tosca Tango Orchestra, except for one piece of Frédéric Chopin’s that was used. The soundtrack was relatively successful. Featuring the nuevo tango style, it bills itself “the 21st Century Tango.“ The tango contributions were influenced by the music of the Argentine “father of new tango“ Ástor Piazzolla.
