As with many new popular musical styles, swing met with some resistance because of its improvisation, tempo, occasionally risqué lyrics, and frenetic dancing. Audiences used to traditional "sweet" arrangements, such as those offered by Guy Lombardo, Sammy Kaye, Kay Kyser and Shep Fields, were taken aback by the rambunctiousness of swing music. Swing was sometimes regarded as light entertainment, more of an industry to sell records to the masses than a form of art, among fans of both jazz and "serious" music. Some jazz critics such as Hugues Panassié held the polyphonic improvisation of New Orleans jazz to be the pure form of jazz, with swing a form corrupted by regimentation and commercialism. Panassié was also an advocate of the theory that jazz was a primal expression of the black American experience and that white musicians, or black musicians who became interested in more sophisticated musical ideas, were generally incapable of expressing its core values. In his 1941 autobiography, W. C. Handy wrote that "prominent white orchestra leaders, concert singers and others are making commercial use of Negro music in its various phases. That's why they introduced "swing" which is not a musical form" (no comment on Fletcher Henderson, Earl Hines, Duke Ellington, or Count Basie). The Dixieland revival started in the late 1930s as a self-conscious re-creation of New Orleans jazz in reaction against the orchestrated style of big band swing. Some swing bandleaders saw opportunities in the Dixieland revival. Tommy Dorsey's Clambake Seven and Bob Crosby's Bobcats were examples of Dixieland ensembles within big swing bands.
