I don't know what it is about the Adrenalize album , but whenever I see it mentioned I am filled with awe . But really , I do know . Despite being at first slightly disappointed ( which a lot of people were unfortunately , it was obvious due to the sales ) now I love it . The reason is the concert , Def Leppard , fresh out of the studio and having mastered their stage performance , were unbelievable . Incredible , the lazer display was something that you just had to see , I was hypnotized seems like a good way to put it . The best concert I've ever seen and that's saying something compared with Rush , Plant and Page , Pink Floyd ( Gilmore ) lol . Now it's just a memory . I just have to put it out there anytime the subject is mentioned .
