Alban Berg’s work Lulu is rarely performed.  With Schoenberg as a teacher, the music from this second Viennese composer is 12 note music and atonal.  The opera was left unfinished at Berg’s death in 1935 and the complete opera was not performed in its entirety until 1979 when the Paris Opera, under the baton of Pierre Boulez, brought the whole 3 acts to a wider audience.
