these guys are so good. they formed a band and they have played at madison square garden and the kennedy center. these soldiers are becoming whole again because arthur has filled the silence with the notes and melodies that keep all of us alive and dreaming. take a look. ♪ >> music makes sense to me. it's how i'm wired. i just go from one musical experience to the next. that's been my life. i never decided to be a professional musician. it's just what i've always done. when i first came to walter reed, i learned that injured troops were being saved due to incredible advances with battlefield medicine. but the injuries are extremely complex and in many cases catastrophic. imagine you're this young, active, bright soldier.
