Juvenile delinquent

      "Do I dislike any instrument? Well, I am not very fond of the two most conspicuous instruments of the Lulu orchestra, the vibraphone and the alto saxophone. I do admit, however, that the vibraphone has amazing contrapuntal abilities; and the saxophone's juvenile delinquent personality floating out over all the vast decadence of Lulu is the very apple of that opera's fascination."
