The Ferry Costen track from Trance-Energy 2005 can be download at ***. Here there is also a 1 hour track from Yoji Biomehanika, one of the other artists of this event, wich has been mixed at the 1 hour before he did trance-energy. Also mixes from other events can be downloaded here and all for free. So forget that 7,70 euro and download for free.
EDIT: Sorry, no mp3-links...
