Query: Big disappointment

As already mentioned above: there is less than 20 seconds of actual performance in this video. While learning about the drummers is fascinating, it is not what i paid 20 bucks for!! I am incensed at the misleading editorial on the DVD, which doesn't even *HINT* at the fact that this is a documentary, not a performance. I didn't get what I paid for. Unacceptable business practices: just shooting themselves in the foot. You don't buy a car only to find out there's a vcr in the dash with a guy telling you how the car *would have* run if it were real... in another language, no less. I might have purchased this DVD if I had known that it had no performance, but I feel cheated now.
