Stardom in metal? Cool story, bro. Metal is still largely considered as niche. Most metal fans will still mostly listen to largely unknown groups.
Because, let's face it. Apart from Lordi and Marilyn Manson, how many metal groups have attained stardom? Sure, some have a large fanbase, but this fanbase is still tiny compared to the total population.
Hel, I suspect very few people will even recognise the names of my favourite groups. Aephenamer, The Vision Bleak, Hoth, Ereb Altor and Therion. So, do any people know them around here!
