Darius Rucker and 25 participants in last year's ACM Lifting Lives Music Camp program will perform "Music From the Heart" during a special segment of the 46th annual Academy of Country Music Awards show taking place Sunday (April 3) in Las Vegas. The music camp, one of the ACM's charitable endeavors, is attended by young people with developmental disabilities. The campers wrote the song last summer with songwriters Brett James and Chris Young. Julianne Hough will introduce the segment supporting Nashville's Vanderbilt Kennedy Center in its efforts to help make positive differences in the lives of families dealing with developmental disabilities. For the past six years, the center has hosted a music camp for people with Williams Syndrome, autism and other developmental disabilities. Viewers may make a donation of their choice to the Vanderbilt Kennedy Center by dialing 1-888-9-LIFTING or make a $5 donation by texting DREAM to 27722. All proceeds will benefit the Vanderbilt Kennedy Center. CBS will broadcast the ACM Awards from the MGM Grand Hotel at 8 p.m. ET/PT.
