When I bought this video, I was expecting to see actual concert performances of the songs on the listing. To my horror,there were only a few edited concert footage and they were all dubbed with the music from the audio CD. For the other songs,it was worse. It was just Christina in the studio, singing to the microphone all the time with the exact sounds from the audio CD!!
Christina Aguilera, unlike some singers like Celine Dion (who sings live in the same way she sings on her CDs) , has a talent in improvising her songs during her live performances. This video should have featured her actual concert performances - undubbed and unedited! I am sure, in her live performances, she could come up with many new stylisations in her songs which alas, I did not hear much in this video. I did not buy the video expecting to hear the same sounds which I could have got from the audio CD.
The video is really only worth the two songs that are not found on the audio CD - At Last and The Christmas Song. I felt there wasn't much new nor surprising stuff here. As for the talk Christina gave on the video, it wasn't exactly inspiring either.
VERDICT: Borrow this video if you can.
