band with this logo: skull in pyramid in (wireframe) sphere

[frost punk]

this is about a rock band who's logo I found randomly yeeeaars ago I was a child found it on an old dark site, it were people with long hair and beards like black sabbath but their logo was a skull in a transparent pyramid and the pyramid was in a wireframe sphere, I really don't find them back with typing those words in google, maybe someone knows them? http://i50.tinypic.com/35jjr5x.jpg , this is a fast sketch I made
