Country super-duo Sugarland will headline the first-ever "ACM Fan Jam": a fans-only live concert event that will take place at the Mandalay Bay Resort and Casino in Las Vegas. Occurring during and after the 46thannual Academy of Country Music Awards, which will be broadcast live from the MGM Grand Garden Arena in Las Vegas Sunday, Apr. 3 (8 -11 p.m. ET, live), on the CBS Television Network, the "ACM Fan Jam" will include three live remotes into the ACM Awards telecast. With tickets to the ACM Awards selling out in minutes, the "ACM Fan Jam" helps answer fan demand for more access to the show.
