Input: Consider Input: Well another one of my first dvd purchases...I found this concert very poor...it did nothing for me... the sound quality was poor, The set on stage was quite good but lacked the final sparkle, Janet's performance was glitzy... but sadly something was missing...my advice is puchase Janet's later DVDS...

Output: Negative


Input: Consider Input: As a survivor of the Woodstock generation these artists play the music I love to hear. The musicians are in excellent shape, the line-up is superb, the selections are well-chosen and the DDS 5.1 mix is a showroom example of a proper live concert mix. Ambient and live but clear and focused. All in all an excellent sounding DVD of some top-flight musicians and songwriters strutting their finest stuff with Sir George Martin adding some very fine string embellishments to many of the songs. If you like these artists and their music this DVD will not disappoint you.


Output: Positive
