For the first time ever, CMT is sponsoring May's "Sizzlin' Country 2000" concert in Los Angeles to benefit the Cystic Fibrosis Foundation. Clint Black and Lisa Hartman Black will host the event, which will feature performances by Lonestar, The Wilkinsons, Bryan White, Jessica Andrews, Chad Brock, Kenny Chesney, Julie Reeves and Chalee Tennison. The evening's other festivities will include the Sizzlin' Country New Artist Showcase featuring Jennifer Day, Craig Morgan, Tammy Cochran and Coley McCabe, as well as dinner, silent and live auctions and the presentation of the CFF's first Heart of Country Award. The award has been established to recognize individuals or corporations for contributions they make to their communities. Bill Lardie, president of Anderson Merchandisers, will be honored with this year's award. The sixth annual concert will be held Tuesday, May 2 at the Warner Studio's back lot, Laramie Street, which was the site of television productions for notable shows such as Little House on the Prairie, F-Troop and Cheyenne.
