Watch Neil Young - Haskell Wexler - Teatro Session (2015) Official Trailer

In the video John Hanlon, producer/recording engineer says: "Neil just captures the moment, he gives it his all, he goes for the throat. If he is not feeling it, he ain't gonna pick up the guitar. If he's feeling music, then he is recording, he's playing and I am recording it because that's what art is, capturing the movement, all the human imperfections, that is what it is about always. He is the commensurate artist, we get first takes on everything, that's the idea, cuz that's often times the best stuff. If you have to think about it that's not creating, that's thinking, then it doesn't work, it doesn't have that passion."
