"Writers have always been quick to heap praise on the soloists, vocalists and composers of the Swing Era but John Wriggle's Blue Rhythm Fantasy finally shines the spotlight on the craftsmen who really made the Swing Era swing: the arrangers. Having done a monumental amount of research, Wriggle invites the reader to listen to the music of the big bands with a fresh set of ears and a fresh amount of appreciation for many of the unsung heroes of that era, most notably the great Chappie Willet. An important book not just for jazz studies but for anyone interested in the entire popular music spectrum of the 1930s and 40s."--Ricky Riccardi, author of What a Wonderful World: The Magic of Louis Armstrong's Later Years and Director of Research Collections, Louis Armstrong House Museum "The unsung artists and business people who were the backbone and lifeblood of the popular music business in NYC in the 1930s and '40s are finally the heroes in this excellent and extremely well-researched book. This exciting new teaching tool brings to the fore those crucial musicians who kept all types of popular entertainment flowing by creatively and professionally combining such diverse job titles as composer, arranger, orchestrator, and copyist."--Benjamin Bierman, author of Listening to Jazz.
