When it comes to mono mixes this one is easily the best sounding of the lot. Utilising original mono tapes (not tape copies), original mono mixes (not folddowns) and no noise reduction, mono is how this stuff needs to be heard!
One of the first 300 or so copies pressed (look at those matrices)! You will hear some light crackle here and there.
