Query: Immortal Album

This album is one of the immortals.I sat on the stage when they played at Chicago's Kinetic Playground in 1969. I was 6 feet from Robert Plant and Jimmy Page. It was the greatest concert of my life. The music BLEW everyone totally away. I wish you all could have seen Robert Plant screaming the word "Gun" from "I got you in the sights of my guuuuuuuuuuuuuuuuuuuuuuuuuuuuuun." He started softly and did a limbo layback from face down to lying totally with back to floor as he did a crescendo of the word 'gun'. The final moments he was facing the ceiling just screaming it out. He MAX'ed it out. It shook the whole house apart. Then the music exploded. It was pure inspired bedlam. God help me, it makes me shiver just to recall it.Immortal is the only word I can think of that does justice to this towering monument of rock history. It is Best in Class.
