Not a documentary, but an interesting interview by Terry Gross of a musician who lost his hearing (& nearly his life) in a terrorist train bombing. Over the course of his recovery, as he listened to recordings at volumes high enough that he could feel the words, he began writing songs, better than ever before. He once said, in an interview with Stu Nunnery (another musician who suffered catastrophic hearing loss), “That was when I became a songwriter. Really that is when I became an artist. Like I found words and texture. Sound is a texture.”
