PLEASE know that the DVD's below (or after "It Might Get Loud", depending on your monitor settings...) are independently produced (unauthorized) documentaries; some are decent quality ("Biography", from The History Channel) and interesting (Robert Plant on the Charlie Rose Show)...yet some are downright poor quality and borderline bogus! Please consult the "Star" system (5 being the best and 1 being the worst), in addition to the Customer Reviews when considering your purchases. These items are offered for collectors who are curious, as well as "completists"; some are cool and some are...less than that!
