I think it's US based (as I pay $9.99 per month!)
It's a usernet group. Not very pretty but pretty comprehensive. My taste is a little "leftfield" (maybe not as specialist as your's Ant

) but I can ususally find ~80% of what I'm looking for.
As I said, it's a great source for pre-release, live, rarities etc - along with standard new releases and back catalogue. It does try and catagorise the music by genre too.
I don't like/trust the pier-to-pier type sites (Limewire et al) so this one works a treat for me. Take a trial and see what you think. I only recommend this site to other true music lovers
Oh - and you can download films/DVDs here too!!!
If I really like the album, or need a better quality recording, I'll do the Amazon thing too.
Let me know if you "get it" and I'll PM you the link for it's global search tool
