I have a vivid memory of the first time I heard Dark Side of the Moon. It was Spring of 1973. I was at my friend’s house and his older sister put on the album in the other room. I stopped what I was doing, stood up and said “What is this music? I have to know. I walked into the living room and she showed me the album cover. It was life-changing. I’ve listened to that album (and all the subsequent albums) many times over the years and have many friends who share the love of this music. Thank you Pink Floyd!
