Kathy Mattea will do a Christmas tour in the coming weeks. Her Good News, released in 1993, is a first-rate holiday album. With 12 dates scheduled so far, Mattea will start Nov. 30 in New London, Conn., and finish Dec. 20 in Shenectady, N.Y. She has two shows scheduled Dec. 4 & 5 at B.B. King's Blues Club in New York City. A new Christmas concert TV special, Sounds of the Season With Kathy Mattea, will air on public television in 20 markets nationwide, distributed by American Public Television. Mattea recently split with Mercury Records. She has begun work on a Celtic album, with plans to undertake several other recording projects. "She has options," a spokeswoman says.
