I must confess I coudn't resist and downloaded the CD. And I must say the sound of the band is really very poor and Steve's singing too sometimes (not to mention vocals). At least in comparison to other Steve's live recordings, especially with other Dukes. Roscoe is probably a little innovative but still, there are songs we know practically by heart, just played and sang much worse than we know them. 
I will probably buy the DVD one day, but it's somewhere at the bottom of my "to buy" list.
