I finished listening just now and went back and listened to Green River on the 10cd set. The sound on the CCR disc seems sharper than the sound on the 10cd set. Aside from the sound, what the 10cd set lacks that the single disc has are incredible extended performances of Keep on Choogling and Susie Q. They’re worth the price of the disc. You can tell (and feel) the effect that Keep on Choogling had on the crowd. It was electric.
