"We're in the age of Pro-Tools," Jack says. "Fixing things, Auto-tuning, removing mistakes or tiny little clicking sounds and any extraneous noise or tape hiss. If you listen to the radio or a modern song, you don't hear any of that stuff. I think all of that is soul to me, though. That's the good stuff."
A couple of clips here from the It Might Get Loud documentary featuring Jack, Jimmy Page and The Edge. In the first clip, Jack speaks about his favorite song from Son House. The second clip has him playing a bit of "Fly Farm Blues".
