The fourth edition of the Rock to Recovery concert and salute is coming together, with System of a Down’s Shavo Odadjian joining the performance lineup, while musician-turned-producer John Feldmann will serve as one of the night’s honorees.

The event will take place Aug. 24 at the Fonda Theatre in Hollywood, with music featuring veteran band Goldfinger and Sacred Sons, with the latter consisting of musicians whose credits include Korn, Sevendust, She Wants Revenge and Madonna. Odadjian will be sitting in with Sacred Sons for the night.

Feldmann, Goldfinger’s frontman and producer for such acts as Blink-182 and Andy Black, will be saluted with the Rock to Recovery Service Award, while the night’s other major honor, the Rock to Recovery ICON Award, will go to actress-singer Katey Sagal. Both honors salute those who have used their power of influence to help put a spotlight on addiction and recovery while giving hope to others.

Wes Geer, founder of Rock to Recovery, says, "What most people don't know about Katey is she is an incredibly talented singer, came to L.A. to pursue music, than just happened to get on one of the most successful sitcoms of all time as Peg Bundy on Married with Children and then winning a Golden Globe for her role as Gemma on the smash Sons of Anarchy. But aside from being a singer, and Iconic actor, she has been in recovery herself for a very long time, and always made herself available to help carry the message of hope, and be of service to those in need."

As for the Rock to Recovery program, Geer states, “This fundraiser raises about 90 percent of our annual revenue. With this money we partner with the Dept. of Defense, working internationally with wounded veterans. We work at local VA's, with veterans with spinal cord injuries, youth correctional facilities, indigent rehabs, wherever we can help people. We bring them all hope through our musical programs. In most of these programs, this is the group they will not miss, they fight for the opportunity to be there. For people who have been lost to the darkness for so long, Rock to Recovery brings them light in the most magical way — through playing writing, performing music. I think an injured Air Force veteran said it best when she explained to me that 'Rock to Recovery helps to put a song back in their heart.'"
