I have had "Antony Hegarty" listed on my New Discovery list for almost two years - so I guess I can't call him a New Discovery.
Flipping through the channels one evening, I came across a tribute concert to Leonard Cohen. I was half paying attention until this astonishing voice came on. This is what I saw. Unfortunately, "embedding disabled by request".
I stopped in my tracks and watched with my mouth agape for the entire time. What an incredible voice.
Antony (and his band The Johnsons) made their US network television debut on Late Night with David Letterman:
They have also appeared on one of my current favorite shows, Sundance Channel's Live from Abbey Road.
