I think it was in '73. I was listening to the radio and on comes a song that shook my rock foundations - I didn't catch the title of the song, but it had just been released ......later I found out it was Money. That demonic hypnotic riff got me hooked forever. Since then, I started digging into the earlier stuff and discovered psychedelic nuggets like See Emily Play, Arnold Layne and Careful with that Axe, Eugene.....it was a retro thing for me.....the rest is history.
Paradoxically, I felt indifference for The Wall and I started to lose interest in PF
