Nelson Riddle and His Orchestra was a prominent force in the American music industry during the mid-20th century. Known for their complex, jazz-infused arrangements, the orchestra played a crucial role in the development of the "Easy Listening" genre. Under the leadership of Nelson Riddle, an influential arranger and composer, the ensemble collaborated with iconic vocalists such as Frank Sinatra and Ella Fitzgerald, contributing to several of their most successful albums. Key works include "I've Got You Under My Skin" and "Witchcraft", which showcase Riddle's signature blend of lush strings, brassy swing, and intricate rhythm sections.
