Those lovely folk at Box Emissions have very kindly released the first "official" Zpg tape.
Go here for details of how to buy. There should be some sound clips on their bandcamp soon.
The tape features two long improvised tracks, 'Dipylon Gate' and 'I went to Frogtown'. Take some time to check out the awesome 'Hell Comes to Frogtown' starring the one & only Rowdy Roddy Piper as a man with a top secret penis.
