LUSH LIFE-Piano Magic   At 21, Billy Strayhorn wrote a marvelous and highly sophisticated song, both in its construction and with his world-wise lyrics. Sinatra, despite all his talent, felt he could not do justice to the song and stopped trying.
This is an instrumental version by the highly prized Geri Allen.
Even though the song features highly complex harmonic passages, Geri Allen adds her own harmonic richness, especially in the opening section without accompaniment. It offers a textbook example of distinctive improvising around an almost perfect compositions. The richness of her piano sound is breathtaking.
She proves that one can improve upon perfection.
