El Extrano de Pelo Largo is both an excellent rock and roll movie and a good sample of the Beat Argentino music scene in the late 60′s. In fact most of the actors are pop musicians, like Litto Nebia (the top star of the movie), who does a great job acting and singing the same ballad, "Rosemary", again and again. There are great musical scenes, interesting dialogues and very good music. The movie looks very good, very psychedelic.
