Fusion of fusions is not a bad way to describe the band! The fun thing about King Gizz is just about every one of their albums incorporates a completely different genre than the one before, although at their heart they're a garage/psych band. Their latest release is a thrash metal album that sounds a bit like what might happen if Metallica had a love child with Black Sabbath.Actually not bad.
But it's like a fusion of fusions by my completely music illiterate ***. I do get a strong Doors vibe.
