I suppose the biggest musical influence on me was my parents, though to this day (I'm about three months shy of 66) I'm not entirely sure whether I care more about the music itself or the particulars of its reproduction.
I loved my mother's circa 1954 Voice of Music changer and constantly played records on it, but I was at least as fascinated by the record player itself as I was by the music.
My mother had been a Columbia Record Club member in the 1950s, though I think that was probably one of the first things to get sacrificed after I infested her womb. Either that, or my father just nagged her into cancelling. But by that point she had dozens of LPs, pretty much entirely easy listening and classical, so for the first few years of my life, that's all I ever listened to. I don't remember having any other music specifically forbidden or withheld from me, but for the most part, if they turned on the radio it was either an easy listening station or KFBK 92.5 FM, which I specifically mention because I'm sure one or two others here have memories of it.
She also had a collection of 78s, some of which my pack rat-averse father forced her to give away along with at least three 45s that I can remember being around when I was tiny but haven't seen a trace of in close to 60 years. The 78s that survived have all been carefully digitized.
Family legend says that a teacher once asked me what my favorite song was and I said it was Handel's Water Music (specifically the Eduard van Beinum/Concertgebouw orchestra version on Epic, not that I would have gone into that level of detail at the time). The story goes that the teacher thought that was weird enough to mention to my parents. Whatever.
I can remember other kids in school making references to popular songs of the day, but I had no clue that's what they were doing. I specifically remember mentions of "the little old lady from Pasadena," what I now know was "The Name Game" and whatever the song was that included "Three six nine, the monkey drank wine" but to me that was just some random interesting (to a six year old!) thing kids were saying. In fact, I think I was north of 50 when I learned that "three six nine" was used in a song.
At some point I was given a little tabletop AM-only tube radio and explored a bit more on my own. I somewhat remember going through a country phase ("KRAK radio, eleven four-oh!") around the time "Little Arrows" and "Big Daddy's Alabammy Bound" were getting played. And probably "I've Been Everywhere, Man."
I never completely lost interest in classical music, though for a time I was pretty dismissive of easy listening. Certainly by the late sixties I had discovered AM rock radio and by the mid-seventies had become absolutely addicted to "underground" FM rock radio, specifically KZAP 98.5. I can remember a time when the Beatles were my favorite act, though at some point I became more obsessed with Elton John and then, after realizing that three songs I used to hear all the time on KZAP were from The Dark Side of the Moon, I took the bus to buy the album in the summer of 1974 and within a few years had become an incurable Pink Floyd fanatic. To the extent that I still have anyone that might be called My Favorite, it's still them.
But along with the music, I was also obsessed with sound quality and preferred reels to records, FM to AM, etc. I thought (and still think) that CDs were the greatest advance in home music reproduction ever. In fact, when people first started murmuring about putting their CDs on hard disk, I thought it was the stupidest idea I'd ever heard. I mean, CDs were already perfect the way they were, and hard drives were small and expensive, so why the hell would I want to use a computer to play back music?
Skip ahead 20 or so years and I started dipping my toe into the world of playback from hard drive, eventually acquiring several Logitech Squeezeboxes, when then developed into an all-consuming obsession with getting my entire CD library online. I was still years away from retirement, working full time and had a library of well over 1,000 discs, but once I started I couldn't stop until I'd finished. Took me about 18 months overall, so you'd better believe I have an extremely robust backup routine!
I still enjoy just about every type of music that I ever enjoyed (well, maybe not kiddie records so much), but I'm also at the very least equally obsessed with the playback technology. And also obsessed with the fact that tags in FLAC files can be used to store an enormous amount of information about the recordings. In fact, now that LMS includes the ability to read WORK tags, I'm going back and adding them all my classical files.
When my mother died I took the only stuff of hers that I ever wanted: The record collection. I've digitized some of my childhood favorites, even going so far as to find replacement copies when the originals were too damaged by either her casual treatment or, far my likely, my stupid little child fingers.
As far as I can tell, to this day my father only voluntarily listens to classical music, though he was never much of a collector. In fact, about a year ago he gave me his entire CD library, which was only about 25 or so albums. Of course, I immediately sucked all the bits into the computer!
So I guess my mother started my obsession with music + technology, both parents got me interested in classical and AM and FM radio exposed me to a ton of things I'd never previously been aware of.
