..... because to date I find that so many music dvd's are disappointing. And this one is pretty damn fine. Lots of her greatest hits- however, my favourite tracks are #15 (Marvin Gaye's Trouble Man)and #16 (Nothing Can be  Done). Mitchell comes over as genuinely enjoying the audience and doing the  performance. Nobody can doubt she is mega talented. Audio quality- not too  bad at all- (I've heard a lot lot worse- for instance the highly over-rated  "Sessions at 54th Street" has some really bad recordings with  virtually all of the sound coming out of the rear speakers- Uggghhh!). I  just cannot understand the reader who said that the audio quality was  totally inadequate because it could not get his woofer moving- this guy  must have been watching too many Batman dvd's!
