3 Doors Down have built their career on the back of an endless parade of melodic rock radio hits. But it's their tireless work with the US Military that has made them the go-to band for the Armed Forces these past few years. "It's the least we can do for these troops and we'll always find time to play for them if it lifts their spirits," 3 Doors Down guitarist Matt Roberts tells Noisecreep. We're in West Los Angeles with Roberts and his bandmates where they're volunteering for their latest passion project.

The band is here with The Home Depot Foundation, The Mission Continues and local volunteers, to refurbish the exterior grounds of New Directions, a nonprofit organization, which runs a residential program on the campus of the West Los Angeles Veterans Administration Medical Center. New Directions provides an array of services for homeless veterans recovering from "Invisible illnesses" including substance abuse, mental illness and post-traumatic stress disorder.

"We've had a long connection with the Military and the troops, so this was just another way to get involved. The hope is that our fans learn about what we're doing and try and to help out too. We're having a great time working with The Home Depot Foundation on this," says Roberts.

Noisecreep asks the guitarist if he and the rest of the guys in 3 Doors Down have family in the Armed Forces. "Yeah, everyone in the band has some kind of connection to the Military. My grandfather was a World War II veteran in the Air Force, as was my uncle. Brad's [Arnold, vocals] father was in the Air Force and he's got siblings that served too. So we have a deep understanding of what it means for these families that have loved ones serving our country."

Roberts says a trip to Walter Reed Army Medical Center was a sobering reminder of the horrors of war. "It was heartbreaking to see what some of those soldiers had to go through. Listening to some of their stories really got me. But at the same time it feels great to know that music can be medicinal. Just to know that in some teeny-tiny way we could help them through a tough time is gratifying."
