Nice to see a few of you are wondering in to see what techno is all about... If you've got any questions about the style, I think I speak for most of us here (well I definitely speak for me anyway!!) when I say post your questions here and we'll try our best to help you.
Best thing you can do is to try joining a few on-line shops and narrow down the style/artists that you like. Do a bit of research and then join in the real discussion!
