Rolling Stone and Gibson have teamed up to offer a special weeklong series of music performances and the first-ever chance for music fans to make a charitable donation to support musicians and walk away with a signature guitar. First up is James Bay, who kicks off his set with “Scars,” from his 2015 LP, Chaos and the Calm. Bay tells the camera that the track is about “realizing when you’ve lost something or someone, [and] that person or thing was so vital to you,” he says, “that you can’t make that mistake again.”
