Chris Buck’s best photograph: Billy Joel in the dark with an Applause sign

Billy said, Ill do this but Im not one who performs because of an urgent need for approval

I had seen the sign about eight months earlier at a prop house. It was just an odd piece that caught my eye and belonged in a daytime TV studio, to flash when the audience should clap.

When I got to the hotel suite with my assistant the journalist was interviewing Billy Joel in another room, so we set up in the bedroom. We stripped off the sheets, plugged the sign in and I pulled the curtains closed until I felt there was the right ratio of light between the sign and the room. I wanted the room to be dark, but with just enough light to see what was going on.

A few minutes later Billy came in and said: Ill do this but those who know me will tell you that Im not one who performs because of an urgent need for approval. He understood that we were framing him in a vulnerable way, but at the same time he thought it was a cool idea. We shot a couple of test frames, but when we began to shoot in earnest he asked: Where are your lights? I explained that this was it and he said: Youre fucking crazy, man.

At a certain level, people get used to a lot of bells and whistles. But theres no need for that kind of affectation. Some of my favourite photographers, like Robert Frank, shoot in a low-key way with only available light. I get people to do things for the camera, because I believe in my ideas. Im more likely to tell than to ask. My genuine excitement gets people on board. Of course, it doesnt work all of the time.

I took this in 2001, for a US music magazine. Theyd sold the shoot as just a few minutes in a hotel room. Those low expectations were an invitation for me to reach for the stars and be really creative. I always try to make images, especially of very famous people, that are surprising. By making this picture dark, Im subverting the portrait the Billy Joel-ness is secondary to the mood of the room and the message of the sign.

I also did some straighter portraits and shot in colour as well as black and white, because I knew I had to cover myself. The magazine used a vertical, colour version of this image. The sign is tungsten, so in a colour photograph it looks very orange, but in black and white there is more of a sense of the room and the light merging.

Im not really a fan of Billy Joels music. He was a nice guy to photograph, but Im more likely to change the channel when his music comes on the radio. He said he wanted me to shoot his album cover, but he never got back to me. It is rare that I hear back from someone like him, and its not what Im there for. I believe that photographers are journalists and our role is to critique people who drive culture, so its not in my interest to become tight with the people I photograph.

Anyone who has made sacrifices for their profession against such terrible odds of success is clearly looking for some kind of affirmation. They want and need some love from the world. My photographing celebrities is about that, too, and in a way this picture is more about me than it is about Billy Joel. The best portrait photographers brazenly prod and manipulate their subjects into essentially making self-portraits, so Billy is a stand-in for me; I want the approval and I want the applause.
