(AP) - Vince Gill, Ricky Skaggs, Lee Ann Womack and Buddy Miller will help the Country Music Hall of Fame celebrate the opening of its expansion.

They will perform at a grand reopening ceremony on April 15 that's open to the public.

The museum will open 10,000 square feet of new exhibit space that will include a hands-on interactive display about current country music and a window on museum staff working on actual archival projects.
