This being a new documentary interviewing many, many people that will explore why music enthralls and fascinates, why it endures and evolves and is timeless and new. Hopefully the documentary will also explain why music inspires such mounds of hopelessly overwrought and self-conscious criticism, too. Because that's something we'd really like to understand better, and I think Elijah Wood's just the person to tell me.
And no, I have no idea why the trailer plays twice.
