Because press agents dubbed him "The King of Jazz" in the 1920s, Paul Whiteman has always been considered a controversial figure in jazz history. Actually, his orchestra was the most popular during the era and at times (despite its size) it did play very good jazz; perhaps "King of the Jazz Age" would have been a better title.

Originally a classically trained violinist, Paul Whiteman led a large Navy band during World War I and always had a strong interest in the popular music of the day. In 1918, he organized his first dance band in San Francisco and, after short periods in Los Angeles and Atlantic City, he settled in New York in 1920. His initial recordings ("Japanese Sandman" and "Whispering") were such big sellers that Whiteman was soon a household name. His superior dance band used some of the most technically skilled musicians of the era in a versatile show that included everything from pop tunes and waltzes to semi-classical works and jazz. Trumpeter Henry Busse (featured on "Hot Lips" and "When Day Is Done") was Whiteman's main star during the 1921-1926 period. Seeking to "make a lady out of jazz," Whiteman's symphonic jazz did not always swing, but at Aeolian Hall in 1924 he introduced "Rhapsody in Blue" (with its composer George Gershwin on piano) in what was called "An Experiment in Modern Music." Red Nichols and Tommy Dorsey passed through the band but it was in 1927, with the addition of Bix Beiderbecke, Frankie Trumbauer, and Bing Crosby (the latter originally featured as part of a vocal trio called the Rhythm Boys), that Whiteman began to finally have an important jazz band. Joe Venuti and Eddie Lang soon joined up, and many of Whiteman's recordings of 1927-1930 (particularly the ones with Bill Challis arrangements) are among his finest.
