Roger Waters, but yeah, I can see how you thought that.
Interesting you see Diamond Head pretty much the same way I do: ruined by mummy-management, poor promotion and an arrogance in their own fanbase that eventually lost it to them. The final straw was the "Grim Reaper" stunt: what a tool! DH could have been so so much more, but when a band (only starting out) gets ideas above their station it's a slippery slope.
I thought it was hilarious that the Metallica fans thought Diamond Head were covering Metallica when in fact it was their own song Metallica had covered! Just shows you, perception is everything!
