RCA/BNA labelmates Kenny Chesney, Sara Evans and Jennifer Day will hit the road together in October for "Making Music Matter," a series of free concerts sponsored by Maytag Appliances and the U.S. Dept. of Energy. The tour seeks to promote conservation of the nation's natural resources. The six-city schedule kicks off Oct. 28 at Boston's Symphony Hall then heads to New York where the artists will appear in the Macy's Thanksgiving Day Parade on Nov. 23. The tour continues into 2001 with Phoenix in January, Los Angeles in February, Chicago in March, and Washington, D.C. on Earth Day, April 22.
