The unreleased tracks are listed on the triskele website with "*" next to them,
The ORb and Infected Mushroom both have unlreased tracks on there.
Well I think you just answered your own question.
Putting out a triple CD in just one month is an amazing amount of work - there's no way to get new tracks from every artist unless everyone is happy to wait another 6 months. Chris is no doubt incredibly busy getting this compiled, mixed, mastered, promoted, distributed etc. etc. so he probably doesnt have time to answer everyone he'd like to just yet.
I think it's an exciting project and the first of its kind (?) in the psy trance area - time to show we can offer something positive rather than just going and partying on their beaches (Thailand etc).
