Although they have strong ties to the world of classical music, on this stellar CD, Amy Burton, Patrick Mason and John Musto turn in loving performances of 19 pop songs from the Great American Songbook. "Got a Little Rhythm" covers roughly a century of America's musical styles and attitudes, with juggernauts from many of the revered masters (Gershwin, Berlin, Porter, Kern, and Rodgers) as well as composers as disparate as Nat Ayer and Fred Hirsch.
