newbie

first.. id like to say hello to all of you.. new to this forum, new to this music..
loving what ive heard so far.
ive been exploring some portishead, massive attack,p morcheeba, goldfrapp, nitin sawhney etc etc.. but its mostly stuff ive taken from friends.
most record stores are rather limited in what they keep.. i guess its the $$$ factor.. im in sydney if anyone knows where i can get some cd;s..
any other places i can look?
any help would be much appreciated..

peace love
moonlight

ps: anyone heard of a band called lady and bird? or am i just imagining things?
