The director was there for a Q&A and the question came up about why he there were no interviews with band members and none of their music. His response was that he wanted to invoke their presence through the words of others. That in order to capture them as something other than a VH1 special, that seeing them through that filter was the way to go.
It's always interesting to hear why people decide to show certain things while leaving others up to the imagination. I'm sure you have plenty of personal examples from your own work. :)
