It's a shame when a documentary about an artist's life becomes something of a controversy in itself. The fact that Bill Evans's estate weren't brought into the conversation during production raises real questions about who gets to tell these stories and whether having the family on board ought to matter. For music fans wanting to learn about such an influential pianist, this kind of tension can't help but colour how you receive the finished film. We reckon there's a lesson here about doing the groundwork with the people closest to an artist's legacy.
