Lilith is a figure found in Jewish and Babylonian mythology. She usually appears in two different forms: as a brilliant, seductively beautiful woman and as a dark children-eating night demon. This was precisely the approach used for a concerto for clarinet two registers of which can be easily assigned to these two manifestations. From the heavenly brilliance of a sound rich in harmonics, developed from an Indian raga, leading up to a chromatic cluster, the music covers a wide range of melodies, including romantic harmonic and atonal sounds as well as ambiguous, bitonal, sparkling and eerily colourless sounds, viciously parodistic passages and seductive and demonic dances.
