Dont know about this 2008 mastering of the Gas CDs . Compared to the original released in in the end of the 90s and start of 2000; they sound pretty bad, the beat of the distorted drums make the sound sonic strange; like the sound goes up and down, which the old releases dont. The volume is boosted a bit but i prefer the old ones. And the covers a MUCH better too.
I made this test with Gas : Konigsforst.
