Nice, I never realized there are so many cuts on the "Klingon" rhythm. Linval himself has a vocal on the rhythm with "Things Couldn't be the Same". There are two more dubs found on Scientist Encounters Pac Man: "Prince's Wrath" and "The Dark Secret of the Box".
I'm listening to Heavy Metal Dub now and it's better than I remember. It's a pretty good set although probably not in Scientist's top ten. The contortionist space gladiator on the cover is magnificent. His torso and lower half seem to be joined internally with a rubber band à la G.I. Joe.
