For me it was a joke song made by our neighbours (I think it was called "Ripsipiirakka"). It had live guitars and vocals, and it actually sounded quite good sound-wise; that was exceptional at those days, now that I think about it. The neighbours just never released anything over the internet but just made those drunken joke songs for fun. I was around 9 years then, but well, somehow I catched the infection and had ft within a year. Never managed to get anything done with it though, so changed to IT and been stuck with it since then.
So in short, a couple of drunken, anarchist teens changed my life. Or at least half of it. :)
