I always loved music too, but I never really thought about "the moment" until OP asked this question. Thinking about it now though, I believe that it was one Saturday many years ago when my late older brother Paul bought a Panasonic reel to reel at Two Guys. It came with a detachable speakers and a demo tape, and one of the songs on the tape was Time of the Season by The Zombies. It sounded so ethereal and beautiful, and I guess I was hooked from that time on.
When did you get hooked?
For me, it was 1971 in the Mekong delta.....a fellow soldier sponsored a night-time social gathering and had his modest stereo rig set up for the party. I'm pretty sure that a Pioneer receiver (SX-424?) was involved, but the speakers were definitely a lowly pair of Pioneer CS-33s. Paul McCartney's album 'Ram' was on the turntable and the song 'Uncle Albert' penetrated my alcohol/herbal-infused fog in a manner that made me realize I would never be the same going forward. It was definitely a thunder-clap moment, not a slow evolution or awakening, and a huge debt of gratitude is owed to the unknown soldier who started me on my long journey.
