For over a quarter century the Harmony Sweepstakes has been delighting Pacific NW audiences. The show was the inspiration for the hit NBC show The Sing Off that has brought increased interest to the art of a cappella singing. Tonight's winners will represent the Pacific Northewest at the National Finals.

From vocal jazz to doo-wop, barbershop to pop and all styles in between, audiences will be amazed at the versatility of the human voice in this exhilarating evening of vocal harmony singing.
