I've been meaning to start this thread for a while and since the forum has lately been a bit quiet I thought that now would be a good time.
My record collecting began in the late 80s, and back then, when my preferences and favorites were still being established, I was buying all sorts of interesting secondhand vinyl at boot sales, market stalls. etc. Once I'd gotten them home I'd usually have a quick listen and, if the music didn't grab me immediately, the item would go swiftly into a pile that I'd eventually use for part exchange on the next shopping trip. In retrospect there were some items that I really wish I'd been less hasty to get rid of.
For instance, I remember buying a mint condition white label copy of the (pre-Messengers) Modern Man LP "Concrete Scheme" from a local record shop in 1990. They'd had it in stock ever since it had been released ten years earlier, although how they'd been sent a white label copy instead of a regular one I don't know. I gave it a quick spin when I got home and immediately decided that Wastelands was the only track I really liked. So I taped that one song onto cassette and put the LP in the part-ex pile. Regretting that decision years later, I was lucky enough to find another mint copy online, although this one was unfortunately just the regular pressing.
Also in the early 90s I came across a virtually mint copy of the rare Neutron Records compilation EP "1980: The First Fifteen Minutes" (with a minimal electronic track by the pre-ABC band Vice Versa) for just 50p, complete with its original postcard. As with the above example, I played it...didn't really get it...got rid of it.
Two other great examples were an MFSL half-speed mastered LP of Jarre's "Equinoxe" album and the rare 1973 electronic library LP "100% Electronic" by Eddie Warner, the latter costing me just £1 in a charity shop! Needless to say I didn't hang on to them and to purchase decent copies of both nowadays you'd need about £200. Aaaargh!!!
Do any other collectors on the forum have similar sad tales to tell?
