Just heard an ad on Nova969 for a free Miami Horror gig tomorrow (monday 24th January) at Kit and Kaboodle Supper Club. All you need to do is go on the facebook page, I think 'like' it and get on the doorlist. Im not 100% sure on what to do to get on the doorlist though. Maybe post message on the page or call? There are also other decent gigs around australia. E.g. bag raiders and philidelphia grand jury. Gigs will be happening regularly on monday nights I think thanks to Carlton Dry.
Edit: A link without signing in/up to facebook has now been supplied (thanks). It says its for people in the hospitality industry and they can bring a friend. Seriously, I doubt they can even check where you work. Just make up a place when you sign up to get onto the doorlist.
The link is http://tgim.carltondry.com.au/nsw/
I wish they would stop doing things via facebook ffs..
