You are aware Motley Crue, Guns N' Roses and Skid Row were all heavily influenced by Hanoi Rocks and the Rolling Stones aren't you?
yes of course.
but they dont sound like hanoi, and neither do crashdiet.
especially if you listen to hanoi rocks third album self destruction blues and (my favourite) 4th album back to mystery city, they have all weird keyboards and mad noises etc, i just dont think crashdiet sound like a direct clone of them at all.
crashdiet to me sound like a band playing a much more modern and heavier sounding glam metal.
