This could only be one of two things -  a Korean car or a death metal band. Well, they're doing a concert so that rules Kia and Hyundai out. Founded by Christofer Johnsson 1987 as Blitzkrieg, he later changed the name for Megatherion then again to Therion. He probably had no choice - can you imagine the number of metal groups called Blitzkrieg of that begin with 'Mega'? The style also changed from death to symphonic metal, there's more opera and classical elements, you see. Great stuff.
