The nineties formed me immensely as a metalhead. I became a Maiden fan in 1991, but also discovered most -if not all- subgenres and delved deeper into more than a few of them.
I did not ignore Grunge. Not at all. I liked quite a few bands and albums. I had a Nirvana ticket when Cobain shot himself through the head. I listened to stuff like e.g. Alice in Chains, Soundgarden and The Smashing Pumpkins (although that's not that Grungy).
I liked Grunge more than Korn, Slipknot and Nu metal.
I wonder if you,
@Wayne Bond realize, or agree with the notion, that there were many metalheads who went to Grunge, and lots of them (especially in the US and UK) stopped being that interested in what Maiden did. I was still interested. You were. And some others on this forum (to be counted on one or two hands) were. But many were not. I guess it depends on the territory. But I certainly do not think that only the change of metal brought a change to Maiden's popularity (or traditional metal in general). Certainly Grunge had its share, didn't it?
