I've just spent my lunch break listening to your 8BC trax. While quirky indie pop isn't my particular cup of tea, the only real criticism I can offer is that you should work on your mix downs and recording lot more. A few of your descriptions there say stuff like written and recorded in an hour or something and that does kind of show. Put more pride and effort and confidence in to your music and your listeneners will hear it.
You said above that "I have no idea who puts on gigs" look at a local listings guide online, Newcastle must have promoters that don't just put on straight up metal or punk shows, you need to go to some shows armed with load of CDs and talk to the people organising the event.
If you can't go to pub backroom gigs because you're 17 keep working on your mixdowns and recording and honing your craft until you are old enough.
