Thank you very much twentynine for allowing me to share my remaster.
I converted the original mono files into stereo, enhanced the high and mid frequencies to give bright to the original sound. Also cut the bass frequencies that caused the muffled sound. If the original quality was "B/B+" now it really is "A" at least. You can still hear the heavy bass work from Geezer, but Iommi, Dio and Appice were brought to the front, every instrument is much more audible now. Much more clear.
Awesome performance. Black Sabbath / Heaven and Hell Rules!
This remaster would not be possible without the AUD recording from twentynine, thank you for your blessing, man!
