OK, when I was about 14 I attempted my first recordings using my portable cassette recorder, my mothers cassette recorder (which usually resided in the kitchen), some pens and biscuit tins for drums, my piano (which I still have!) and was pretty good at, and spanish guitar (which was a lousy cheap thing and I sucked, the heavy metal mayhem hadn't quite entered my veins yet)
Of course, I'd record onto one, and then play it back, play along and record onto the other.
I would KILL for those first recordings.
What were yours? Do you still have them? If you do, POST THEM UP!!
(After you've remastered them through $10k's worth of sluttiness of course
)
