King Crimson - "In the Court of the Crimson King"
Jethro Tull - "Thick as a Brick"
Miles Davis - "Kind of Blue"
Eberhard Weber - "The Colours of Chloë"
Pink Floyd - "Dark Side of the Moon"
There are many, many more but I also limited myself to five. I was late to the party in discovering Miles Davis and picked up "Kind of Blue" in a record store due to the partial review on a sticker on the record. Not having heard any Miles I took it home and played it having my mind blown. I think I played it every day for at least a month! "The Colours of Chloë" I heard on the radio. I heard one amazing track and thought "I have to find out what that record is". Then they played a different piece of music and I thought the same thing. I wondered when they were going to tell me what they were playing. Two more amazing pieces of music followed and then they finally gave out the play list - all four were from the same album! You can be sure I went out and bought it immediately.
