I am not a particular fan of Ginger Baker nor of the groups he's been associated with over the years. This is NOT a criticism--I am just letting you know that if you don't know who he is or care, you STILL could really enjoy watching this film!
While Baker is most famous for his part in the short-lived rock group Cream (recently admitted to the Rock and Roll Hall of Fame), this only takes up a small portion of this fascinating documentary about this infamous drummer. Like a good documentary, it tries to cover the totality of his life--and shows him in a warts and all portrait. And, like a good documentary, it allows Baker to speak for himself--in addition to all the celebrity interviews and vintage footage.
So why did I like this film so much in addition to it being well made? Well, Baker is an amazingly self-absorbed *##--and film appears to say he is both a brilliant and amazing drummer AND a sociopathic jerk who uses people and is subject to fits of anger and drunken binges. Heck, you even get to see Baker smash the documentarian in the face and draw blood near the end of the film!! Talk about warts and all.
The bottom line is that this film is like watching a slow-motion train wreck. You know it's repellent and awful--but it's never dull and cannot help but entertain you!!
