It was a very varied music landscape, with the big swing orchestras like Tommy Dorsey and Benny Goodman making their mark, though often with middle-of-the-road vocal performances rather than jazzy pieces, although there’s plenty of hot stuff here too. Along with them are the big dance bands who were popular on radio, including g Guy Lombardo, Shep Fields and Eddy Duchin, competing with each other as they recorded the future classics of the Great American Songbook that were coming out of Broadway, Hollywood and Tin Pan Alley, plus some of the top singers of the era, Bing Crosby and Fred Astaire among them. It’s an enjoyable and fascinating musical snapshot of the era, complete with a 12,000 word booklet with notes on each track, and full discographical and chart information.
