Thank you so much everyone for taking the time to give some great advice!
I have been playing around with bands of other 'genres' for about a year now, but as jefftheworld pointed out this is probably doing more for myself than the scene itself, which I think is a totally valid point. It kinda sucks cos I can't really tell people to check out other chip artists cos others in my city aren't gigging yet!
I definately agree with lazerbeat about having accessable gear. I plan on buying a few spare carts (when I have the cash) so I can give them to people who show some interest.
I'm gonna have to whip everyone I know of into action. I think putting a blog or something together like 10k suggested is probabbly a good idea. I can see the benefit of having somewhere people can go to to find information on all the local artists and events as well as general information.
I think the first step I'm gonna take is to put together a NZ comp and just start handing it out at any gigs I play and just start talking to people about it and trying to get more people interested, use the power of word of mouth.
Thanks to everyone for the support and great advice, especially lazerbeat and low gain for taking the time to write so extensively.
Keep it coming, any ideas help!
