The Zac Brown Band and Ram Truck Brand launched their Letters for Lyrics campaign last week at a RAM dealership near the band's home base in Marietta, Ga.

The campaign, which officially gets underway today (May 10), is designed to rally people to write one million letters for servicemen and women stationed abroad. In return, each letter writer will take home a special compilation CD titled, 'Breaking Southern Ground.' The exclusive CD features three new songs from the Zac Brown Band, as well as music from Sonia Leigh, Nic Cowan and Levi Lowrey, who are also signed to Zac's label, Southern Ground.

All U.S. Ram Truck dealerships will serve as collection points and provide letter-writing stations. The letters will also be collected at ZBB concerts. Soldier's Angels will deliver letters to U.S. troops on behalf of the Ram Truck Brand and the Zac Brown Band. Soldier's Angels is a volunteer-led organization with over 225,000 members providing aid and comfort to the men and women of the U.S. Army, Navy, Marines, Air Force, and Coast Guard, along with veterans and their families.

"A lot of them are over there for long periods of time, away from home, away from loved ones, away from all the things we take for granted," Zac tells Atlanta's WGCL-TV of the troops who'll receive the postcards. "There's a lot of really good people. A lot of young family people, a lot of folks that are over there serving our country. They're willing to fight for it and die for it."

Darren Doane, the CMT-Music-Award-nominated director of the band's live 'Pass the Jar' DVD, released last week, and their music video for the No. 1 hit 'Toes,' traveled with the band to the Persian Gulf to document the moving experience, capturing footage of the band performing for troops and meeting individually with the men and women in uniform. Bringing the experience home, Doane has constructed several mini-documentary style videos which will be posted to the Ram Trucks website starting today and updated throughout the coming weeks.

"We've had several opportunities to perform for the troops over the past year and each time we were deeply inspired by their positive attitudes and dedication to protecting our country and preserving our way of life," says Zac. "We were so moved that we knew we needed to recognize their efforts in a big way. Our hope is that by combining our experience overseas, our music, and the good people at Ram Truck Brand, we will be able to rally a movement of support for our brave service members abroad."
