The first proper album I bought in summer '77 - after seeing them on TOTP in the famous Fanfare video (in the snow-bound Montreal Olympic stadium) - was ELP's Works album. Not their best of course, but it was a gateway to classical and jazz that I have enjoyed for 45 years. I also loved the Pistols, the Clash and the Stranglers and never really understood why you couldn't like all types of music.
Television's Marquee Moon was another big record for me, new wave guys who played too. Adventure was a huge disappointment and I've always thought Verlaine must have got lucky on the first album. Magazine's Real Life also hinted at that new wave / rock crossover.
Floyd's Animals, Yes' Close to the Edge and ELP's Tarkus, I thought were the pinnacle of art at the time and the last two get an outing every month. Ackerman from Focus has always been my favourite guitarist.
I do remember hearing Blue Monday (in 82?) and thinking this is a new form of music, I loved the Cocteaus and picked up the Tangerine Dream catalogue. My real guilty pleasure has always been hard / heavy rock. So much great music, so many terrible lyrics. I thought UFO, Zep and the rest were brilliant.
Later I entered the Jazz and classical world more seriously and have a large collection of great music - thanks to Keith Emerson!
I try to find new music, but despite my best efforts, I rarely but new releases. There are golden ages of music. For me now isn't one of them, but I keep listening.
