The stars keep lining up for CMT's tornado relief benefit.
Alan Jackson, Gretchen Wilson, Little Big Town, Trace Adkins and The Blind Boys of Alabama are performing for Thursday night's "Music Builds: The CMT Disaster Relief Concert."
The special will air live at 9 p.m. EDT from The Grand Ole Opry in Nashville, Tenn., with proceeds going to the American Red Cross. President Barack Obama, Shania Twain, Carrie Underwood, Taylor Swift and Alabama coach Nick Saban are scheduled to give video messages.
More than 300 people were killed across seven states two weeks ago when a record number of twisters struck. More than 250 people died in Alabama alone.
Performers already announced for the special include Hank Williams Jr., Alabama, Lady Antebellum, Keith Urban and Tim McGraw.
