Schulz-Köhn had written on Stan Kenton (1911-1979), the pianist, composer, and arranger. Kenton was born in Wichita, Kansas. As a child he learned piano, and while still a teenager toured with various bands. In June 1941 he formed his own band, which developed into one of the best-known West Coast ensembles of the 1940s. In the mid-1940s, Kenton's band and style became known as 'The Wall of Sound', a term used later by Phil Spector.
