The answer to the old riddle “How do you get to Carnegie Hall” is not “practice, practice, practice.” On this Saturday’s (June 4) Sound of Swing, we’ll take you there via two jazz concerts. The first is the ground-breaking 1938 Benny Goodman Carnegie Hall concert billed as “20 Years of Jazz.” American music critic and historian of the Metropolitan Opera, the late Irving Kolodin was one of the first American critics to really pay attention to phonograph records and the classical and jazz performances preserved on them.
