Note this documentary’s subtitle: Robbie Robertson and the Band. The name of this portrait of the legendary rock group – Once Were Brothers – comes from a cut off a 2019 Robertson solo album; the phrase exemplifies, in the singer-songwriter’s words, how he felt about the four other men who stood beside him on hundreds of stages, in dozens of studios and within one extremely famous pink house’s basement. It’s the second part, however, that’s more revealing…especially that telltale “and.” Director Daniel Roher starts by diving into Robertson’s personal musical journey before turning the film’s attention to the former Ronnie Hawkins/Bob Dylan backing band-turned-Rock & Roll Hall of Famers, expanding the spotlight to encompass the quintet as a whole. But make no mistake: This is really one man’s look back in anger, sorrow, joy and sentimentality. “Robbie Robertson on the Band” would be a more accurate description.
