I have the original CD from 1996 and it sounds great but the 2016 re-issue is awesome...that is if you're a Pantera fan like me. Just enough enhancements to the sound that it doesn't take away from the original but adds great sharpness and clarity. I can hear all Dime's guitar overdubs, Vinnie's drums sound like he's in the room with you, Rex's bass rumbles your insides but you can hear every note, Phil sounds like he's screaming in your face! G.S.T.K. is my favorite besides Far Beyond Driven, which I bought both at Best Buy, the original and the 20th Anniversary re-issue. The bonus CD is awesome! Live versions of some of the songs from the GSTK tour and early mixes of many of the songs and a 2016 mix of the title cut. I love the whole album but I really love hearing the early mix of "Floods". It gives me insight to how Dimebag worked his magic in the studio. What his early ideas were...I'm a guitarist myself and record my own music and Pantera, particularly the late Dimebag Darrell Abbott, RIP, is a major influence on my playing and my style...There was only one Dimebag Darrell, coolest dude ever, and there will never be another like him and it's great to hear him so clear and sharp on this awesome re-issue!!
