DAVE LOMBARDO is completly right about the sound,it does have elements of there first albums.i can hear parts of SHOW NO MERCY,LIVE UNDEAD,HELL AWAITS and yes even REIGN IN BLOOD.But thats what i like about the album,you can hear a riff and it might remind you of an older song,and it makes you want to listen to those older albums.its great.it is 'retro' in the sence that you CAN hear those old album influincesses.thanks CHRIS SLAY
