This is a pretty great album. This was something the progressive rock always try to achieve, but sincerely couldn’t.
Keep going.
I experienced the Roaring Sixties when I was going to school and I liked also the classical music. For me it was a real sensation when I heard of the fact that Deep Purple produced this masterpiece! I don’t know how many times I had heard it as well all the records like DP in Rock, Book of Taliesyn etc. etc. And when I met my future wife (not of Tokyo but of South America…) in 1970 in Munich I made her a musical present: A vinyl record of Deep Purple (with the cover of H. Bosch; April, Bird has flown, Lalena, Chasing Shadows, Painter etc.). And we are still listening together this record today after nearly 40 years. At the last AVO-Session in Basel I intended to make her a special gift inviting her for the concert of DP. Unfortunately, all tickets were sold within a few hours. I still hope to listen to DP life – once in my life! DP forever!!!
