I really like this idea. I like that I can directly support Underworld (and this project) by tossing a few $$$ their way. All of us have tonnes of bootlegs etc. that we listen too (some downloaded from UWLive, with more upcoming), for hours on end. Underworld (or their crew) don't see a dime for this, though it's pretty good advertising for how good they can be. And no matter how anti-filesharing you are, some of their rare stuff can't be bought in a manner that directly supports Underworld (i.e. Ebay). So if I can toss some $$$ their way and buy Rick and Karl and Darren (and Ant!) a latte, even indirectly, I'm loving the chance.
Remember, when you buy the tracks, you're also indirectly buying the bootlegs on UWLive....so to quibble over $2 a track or whatever for "Broken Lovely Thing" with some you like, some you don't, seems pointless when you look at the two bootlegs they have up right now being 12 parts and 18 parts, of high quality (soundboard?!?!?) bootlegs. So that's like...$10 for 37 tracks. We are getting a deal.

(And that's not including the 3 other concerts they have posted in the past, and misc random/live studio stuff, which new/old UW fans can take advantage of without peer to peer.)
Heck, I'm more likely to buy high quality bootlegs than the studio material.
Thank-you Underworld!
