Listening to Lulu now. Apparently this is the two acts the Berg wrote. But after this recording was made, apparently the widow Berg allowed a third act to be done - that's the standard version now, but I need to read up on how it was completed. But as with Wozzeck, I'm really kind of enjoying Lulu. Berg's musical language isn't all that different from some film composers who toiled in the sixties and seventies. I really thought I'd hate these but I don't at all hate them and I like them.
