The dynamic entertainers are the first two announced performers for the concert, which will be broadcast live on Nov. 30 from Los Angeles' Nokia Theatre.

Rapper LL Cool J will return as host for the one-hour concert special, with several categories for the 54th annual Grammy Awards to be revealed throughout the live telecast. Tickets go on sale Friday (Oct. 28) at 1:00 PM ET and can be purchased at http://www.nokiatheatrelalive.com/.

Country music has swept the Grammy awards for the past four years, with Lady Antebellum collecting trophies last year in two major categories for their smash single, 'Need You Now.' Taylor Swift took home the biggest award of the ceremony in 2009, winning the coveted all-genre Album of the Year trophy for 'Fearless,' with Alison Krauss and rocker Robert Plant doing the same with their collaborative effort, 'Raising Sand,' in 2008. The Dixie Chicks also took home the Album of the Year trophy in 2007 for 'Taking the Long Way,' also winning Record and Song of the Year for 'Not Ready to Make Nice.'

Additional performers for the Grammy nominations telecast are expected to be announced shortly. The 54th Annual Grammy Awards are set to air Feb. 1.
