Stanley Newcomb Kenton was an American popular music and jazz artist. As a pianist, composer, arranger and band leader, he led an innovative and influential jazz orchestra for almost four decades. Though Kenton had several pop hits from the early 1940s into the 1960s, his music was always forward-looking.
