Songs that made me? A lot of songs growing up were meaningful to me and touched me in different ways.
Joe Walsh "The smokier you drink the player you get" was playing the first time I IV'd MDA.
I was really into early Pink Floyd until Dark Side of the Moon then they seemed to be more commercialized so I stopped listening to Pink Floyd about the time Shine on You Crazy Diamond came out, although I liked Animals album.
Listened to Sly & Family Stone and War for a while. I had a few albums of Hawk-wind, Ginger Bakers Air Force and Alan Parsons Project "Tales of Mystery and Imagination works of Edgar Allen Poe" Electric Light Orchestra and Yes were in my library collection as well as Jethro Tull, The Tubes, and do you remember White Witch? "It's so nice to be stoned... "
Some defining songs would be "I'm a man" Chicago, Edwin Star "War, what is it good for" David Bowie Ziggy Stardust and Spiders from Mars
The first album I bought was Iron Butterfly "Heavy"
Steppenwolf Monster
