Got it last week, and was just able to listen to half of the first CD this morning - GREAT stuff!
As to yr second question, Yazoo has reissued some of their original LPs straight to CD. Other artists - Charlie Patton, McTell, etc. have been given new releases with new remastering. I highly recommend the two (relatively) recent Patton reissues - listening to them for me was like hearing his music for the first time.
