I just found this book, featuring recipes by members from famous metal bands all over the world and all over the metal spectrum:
It contains recipes by acts as diverse as Judas Priest, Rotting Christ (Country Lamb Exohiko, by Themis!) , U.D.O and Melechesh and judging from the pictures the lay-out looks gorgeous.
I ordered it from Amazon UK, a bit cheaper than getting it from the publisher in the USA. Expect a full review (and possibly some recipe tests) soon!
