Who Shot Rock and Roll?

At the exhibit- Who Shot Rock and Roll, I found one photograph to be especially captivating.
This photograph was of Janis Joplin singing at a concert. I took a picture of it, I'm not sure if I was supposed to, but here is that photograph-

Description

The picture was taken in 1968 by David Gahr. He and The Staley-Wise Gallery in New York are the owners. It's is in black and white and approximately 6 x 8 inches. It was done in a gelatin silver print. According to Wikipedia the process is "the photographic process used with currently available black-and-white films and printing papers. A suspension of silver salts in gelatin is coated onto a support such as glass, flexible plastic or film, baryta paper, or resin-coated paper. These light-sensitive materials are stable under normal keeping conditions and are able to be exposed and processed even many years after their manufacture."

A lot of the photographs in the museum were done in the type of printing, which seams to be related to their time period they were shot.

Analyzing

I feel that this photograph expresses the overwhelming power of music. In the photograph Janis Joplin is singing. Her hand is outstretched as if she is feeling that note all the way to the ends of her fingertips.  I assume she is on a stage because there is a bright light to the left of her left hand. She is wearing some kind of bustiere, which also leads me to believe she is in concert. She is also wearing a lot of bracelets and rings. I think this photograph reveals that Janis Joplin was overwhelmed by her gift of music. She is so passionate in the picture and yet her hair looks kind of greasy, like she didn't care much about her looks. There wasn't a lot of information on the plaque next to the photograph, so the interpretation was left to the viewer.

Relate
This photograph shows Janis Joplin being consumed by her music. Two years later, in 1970 Janis Joplin overdosed on heroin in her hotel room. The photograph lets us see up close and personal just how much Joplin's music influenced her actions, and overtook her body, in the same way that heroin did two years later.
