Brantley Gilbert is letting his rocker side out on a new collaboration. He makes a guest appearance on rock band Five Finger Death Punch's remake of the Kenny Wayne Shepherd song "Blue on Black."

Readers can press play above to hear the collaboration, which also features Queen's Brian May and Shepherd himself. In the verses, Gilbert trades lines with 5FDP's lead vocalist Ivan Moody and joins in on the chorus. Shepherd, too, offers vocals, while May straps on a guitar for a blistering solo.

Five Finger Death Punch originally covered "Blue on Black" for their 2018 album And Justice for None. The proceeds from this new, collaborative version of the track will go to the Gary Sinise Foundation, which recognizes veterans and first responders, their families and those in need "by creating and supporting unique programs designed to entertain, educate, inspire, strengthen and build communities," according to the organization's website.

“To raise awareness for and support first responders is a cause that’s always been close to our hearts," Five Finger Death Punch guitarist Zoltan Bathory says in a press release (quote via Taste of Country). "These brave men and women leave their homes every morning not knowing if they’ll ever see their families again. Yet they make a conscious choice to do so for the greater good."

Adds Gilbert, ""Blue on Black" is a song my band and I have covered off and on for years ... Songs are certified timeless when you can come back to them. It’s always a staple each night and one of my favorite songs to perform ... [This new version of the song] incorporates so many different musical perspectives, but our collaboration just works brilliantly.”

Written by Shepherd, Mark Selby and Tia Sillers, "Blue on Black" was originally released as a single from the Kenny Wayne Shepherd Band's second album, 1997's Trouble Is ... The song spent six weeks at the top of the Billboard Hot Mainstream Rock Tracks chart.
