A. The narrator is a photographer who is looking at her photographs she's taken of her best friend. She tells us her life story going through the pictures she's taken of her throughout her life. She seems to be obsessed with photographing her, showing her in good times and bad. She's very interested in how the pictures represent their friendships and the various looks she's given her over time. She's kind of saddened by not having any pictures to show how she looks at her friend and to see the connection through her eyes.

Her friend is a indie/punk rocker who hits fame and goes on tour performing at different venue's. She captures her very essence of style and personality and gives us a solid representation of her life's story. Her fame lead her to drugs and her music went somewhat downhill. They have a falling out but when she finds out her friend has cancer she sees her in the hospital and says her goodbye.

B. It works because even though the scenes jump around, before each scene it has a caption of the photograph or recording of the time.
