It's not too bad -- it isn't Roo artists only, as stated above.
I'm also curious about the "Volume 11" thing. I know the past two years we've got double disc sets, so were they considering those two seperate volumes? Oh well, it's more of a keepsake for me than a really good mix.
They don't need to sell them. it's a promotional CD. Record companies pay to put their artists on the CD to promote upcoming or just released albums. That is why not all of them are all Roo artists, and that is also why they are free. And Jason is Correct, superfly hands a new volume out anually at Jazz Fest and Bonnaroo, which is why we are up to #11.
