From Fretboard Journal #26:
"It's like watching a tightrope walker and you see them fumble for a moment," he explains. "You're reminded that someone is actually doing something. You hear some part of the instrument and you're reminded that its not an anonymous, uniform thing. Somebody's banging on a tight wire, with their bare hands. You should get a few coughs and rattles out of it." - Joe Henry
I couldn't possibly agree more, Mr. Henry.
