What exactly is the ZZ Top Sixpack (3 CD set)? I've heard many conflicting statements: 1. It's simply the first six ZZ Top albums, period. 2. It's the first six albums, but (poorly) remastered. 3. It's the first six albums remixed and remastered. 4. It's the first six albums remixed and remastered, plus some of the tracks are actually different versions. Can anyone with a pair of cheap sunglasses make some sense of it all?
