Dark Star

Listened to this for the first time the other day (I know, I'm a newbie).
This version completely melted my face off. Phil's melody in the beginning is simply fantastic.
If you want to listen, I recommend grabbing the official release over the Archive versions. The Usborne matrix is good, but the official release gets rid of a lot of the warbling problems in the soundboard.
In my humble opinion, this one should be higher on the list. But I will admit that there is a lot I haven't listened to yet.
