Andre Previn is a pianist, composer, conductor and arranger masterfully standing astride two musical genres … both classical music and jazz. Many fans don’t realize that he had one foot in jazz before his other became firmly planted as a classical musician. Here we sample a touch of his conducting, arranging and piano artistry with “Rhapsody In Blue” before stepping back a few years into a swinging performance of Lerner and Loewe’s “Get Me To The Church On Time.”
