I read the only review for this item and ordered it, expecting to see a fantastic display of sound and some of the interaction of these artists with Mr Hancock as they created music, each colaborating to have a unique blend of sounds.Actually this is only a documentary showing this interaction, and as such is very interesting.But if you are looking to see an hear the full length videos of these great colaborations you will be disappointed, that is not included in this dvd. Only small samples are there for you to see.This was a real disapointmet because the quality of video and audio are fantastic.
