Painted Shield. The track, which is available now as a digital download and via streaming services, is a meditation on âthe moral injury experienced by many service members as they return home from conflicts abroad.â âThe lyrics to this song were inspired by the stories of friends of mine who have served in the military,â says vocalist Mason Jennings. âIt touches on the recovery work needed to integrate back into civilian life after being in conflict.â With â4th of July,â Painted Shield is also hoping to raise awareness for No One Left Behind, an initiative to protect Afghan interpreters from potential danger as the U.S. leaves Afghanistan.
