Disc one has one very light tiny scratch that is very light, probably from being slid in and out of a CD player, but has no effect on it playing whatsoever, you cant even see the scratch unless held to the light cos its not even a centimeter or indented into the disc at all.
Oh, and to continue with the last comment, disc 2 has no marks at all. I only played the discs other than once or twice. Also, even though this is the same concert - Astronomy Domine is more clear on here and longer than the same live version on the 'Take It Back' single B-side.
