WELCOME TO MY WORLD TJ!
My best recommendation is to go to an outdoor dance party, aka bush doof.
Oztrance.com is a great forum to find info on such parties and the music in general. I have a feeling they aren't accepting new members due to hacking attempts, so try Australiens as well.
Mostly my favourite music in this broad genre (psychedelic dance) comes from artists on the Zenon label which is based in Oz and is described as "prog".
Check out Tetrameth, Shadow Fx and Autonomech.
I'm a fan of some darkpsy artists such as KinDzaDza, Baphomet Engine and Datakult.
For the good-old psytrance sound, you should find albums from Hallucinogen, Infected Mushroom, 1200 Micrograms and Raja Ram in most record shops.
Search for any of the artisits mentioned on Myspace to hear samples.
