As previously reported, Sugarland will headline the first-ever ACM Fan Jam and After Jam Party in conjunction with the 2011 Academy of Country Music Awards. Now, it's been announced that additional Fan Jam performers have been added to the lineup: the Band Perry, Eric Church, Little Big Town, Randy Houser and Steel Magnolia.

The never-before-seen musical event will take place before, during and after the ACM Awards show at the Mandalay Bay Events Center.

After winning fan-voted awards already, the Band Perry and Church are also up for New Artist of the Year, and the winner will be presented live on the ACM Fan Jam stage during the awards show. Fans can vote for New Artist of the Year now through April 3 at the official ACM site.

Also on the Fan Jam bill are new artists Bradley Gaskin, Casey James, Laura Bell Bundy and Sarah Darling. The event will be hosted by Bill Cody, and Ticketmaster has tickets on sale now.

Tune in to the ACM Awards on Sunday, April 3 at 8:00PM ET, live from the MGM Grand Garden Arena in Las Vegas.
