Although they are simply four voices and a tambourine, Tonic Sol-fa has spent the past decade on the road carving their niche as the nation's top vocal group. In that time, this quartet has been named one of the top five "must see" groups in America, has been awarded numerous original song and album awards in pop, gospel and holiday genres, appeared on NBC's Today Show and in the pages of Newsweek magazine. Outings with Jay Leno, Shawn Colvin, Lonestar and Garrison Keillor have propelled album sales to more than 1,000,000 copies (mostly sold from the back of their trailer!) and have earned the group thousands of intensely loyal fans. By 2000, the quartet was voted into the Midwest Music Hall of Fame. In 2002, Tonic Sol-fa averaged over 150 shows annually in 48 states. 2005 brought the group's music to radio stations and retail stores nationwide. And in 2006, Tonic Sol-fa's first public television Christmas special was broadcast to over 1,800 stations across the United States, with an international launch to begin this year. The New York Times describes Tonic Sol-fa's sound as "A vocal kaleidoscope...unique to the human voice." Improvisational and passionate music combined with cutting-edge stage presence is the benchmark by which critics and fans agree: nobody does it like Tonic Sol-fa.
