The Hot-Club rhythm popularized in the 1930s and '40s by Gypsy violinist Stéphanie Grappelli and guitarist Django Reinhardt has lit a fire under 1,000 swing-jazz bands worldwide. These two swing-jazz classics capture the flair of that popular music. Â"AvalonÂ" ranges from a waltz to the sound of a carnival carousel. Â"Dark Eyes,Â" an early hit for the fabled Hot Club of France, also starts as a waltz before giving way to chance for you to put a modern stamp on it. Both of these sophisticated swing-jazz charts are perfect for weddings and other casuals or even as concert encore pieces.
