German metal is great, the Scorpions and Rammstein are sure to be the most successful bands the country has ever produced. Scorpions managed what most metal bands strived for but only a handful succeed in doing i.e. becoming massive in the USA. For UK or European bands the US is a vast untapped market that can take years of slog and hard work to break into. The rise of hair metal and MTV in the 80’s gave the Scorpions the opportunity they needed and they grabbed it with both hands.
