Country music trio Lady Antebellum will be honored with the Recording Artists' Coalition Award during the Recording Academy's 2014 Grammys on the Hill Awards, to be held April 2 at the Hamilton Live in Washington, D.C.

House of Representatives majority whip Kevin McCarthy (R-Calif.) and House Democratic leader Nancy Pelosi (D-Calif.) will also be honored for their support of music creators' role during the SESAC-sponsored event, which will include live performances and other tributes. Proceeds from the awards will benefit the Grammy Foundation's Signature Schools, which aids underserved music programs in the United States.

"We are proud to honor Lady Antebellum for their artistry and inventiveness in the country arena as well as their philanthropic efforts to make a difference for disadvantaged children here and abroad," Recording Academy President/CEO Neil Portnow said in a statement. "The Academy is also pleased to honor House leaders McCarthy and Pelosi for their tireless support of music, and we look forward to another incredible evening."

The Grammys on the Hill Awards will also honor Westfield Academy music teacher Kent Knappenberger, the recipient of the inaugural Music Educator Award, presented by the Recording Academy and the Grammy Foundation. The event is expected to draw Los Lonely Boys, Hanson, the Lumineers’ Wesley Schultz, Dionne Warwick and numerous members of the entertainment industry, Washington luminaries, legislators and staffers.

On April 3, the Recording Academy will host Grammys on the Hill Advocacy Day (now in its 10th year), where music professionals will visit with lawmakers to advance policies that improve the environment for U.S. music.
