For many years, Claude Thornhill's orchestra of the Forties and early Fifties was frequently referred to as a musicians orchestra, as it focused as much on the musicians as the music itself. Thornhill's music was clearly way ahead of its time, yet today his sumptuous, mellow jazz sound remains one of the biggest influences for many contemporary big band jazz arrangers. He worked to extend the range of a popular dance orchestra by continually adding new harmonies and voices. In the truest sense of the word, the Thornhill orchestra was an experimental group and this experimentation made mostly exciting and provocative listening.
