So what if Glenn Miller's discovery of his legendary big band "sound" didn't exactly happen the way James Stewart enacted it in the Hollywood bio-pic, The Glenn Miller Story? However it did actually occur, Miller found a tonal blend -- lead clarinet playing an octave above the saxophone section -- that drove swing fans wild, making him the most popular American bandleader from 1938 until his war-related death in 1942. Miller gave the people what they wanted -- which didn't always mean hardcore jazz. Undeniably lightweight at times, Miller's band was also highly musical, with a sound that gave them an unmistakable identity. Hits like "In the Mood," "Chattanooga Choo Choo," "A String of Pearls," "Pennsylvania 6-5000," and "Moonlight Serenade" may not be in Ellington or Basie's league, but for many they virtually define the swing era.
