Claude Thornhill led several of the most innovative bands of the Swing Era.  With french horns, tubas and a clarinet section he created arrangements like "Snowfall" that were almost impressionistic . . by 1947 he was using arrangers like Gil Evans, Gerry Mulligan and Rusty Dedrick who incorporated bebop and soon to be "Cool" influences into his style as well . . great soloists such as Lee Konitz, Danny Polo, Red Rodney, Barry Galbraith and Mickey Folus are also featured on these studio recordings for Columbia and electric radio transcriptions.
