The concept of the successful Swing Quartets, Jazz Quartets and Groove Quartets publications is now also available in a Christmas edition: Bert Lochs has arranged four traditional Christmas songs in a swing style with combo accompaniment. The Swingin' Christmas Quartets are available for trumpet, flute, clarinet and alto saxophone quartets, and all four versions can be combined to create whichever instrumentation you require. The online audio for each piece contains not only a demo version with a full line-up—and a pure playback version—but additionally four versions in which each of the four wind voices is omitted in turn, making them ideal forpractice purposes.
