Best uwrlivecd release/s?

[oHUTCHYo]

Hi guys,

New to the forum. I've been a fan of Underworld for a long, long time but have only recently started to explore their live aspect more, outside of the normal commercial releases.

I'd like to explore the uwrlivecd releases more, as I'm assuming all it's live, the sound quality will be far better than a radio or audience rip?

Two questions really;

1. Which of the uwrlivecd are generally regarded as the better performances (and technical aspect of sound quality etc).
2. Where would one buy the uwrlivecd releases?

Thanks guys
