Jacob Dylan is great but I was disappointed that half the movie was his band. As good as they are I wanted to see more of the original bands doing their own material. And I would have liked to see more of them in Laurel Canyon. I would have also liked to see more of the other musicians that hung out in the canyon in addition to the ones featured in the film. It's when and where I grew up and I felt like something was missing in this. Wish I knew what "echo" signified in the title.
