First, maybe I am too young or way too naive for my own good, but honestly, I have never heard of any of these groups. I am not going to pretend that I have.
Second, what is wrong if I regard Rush so highly as one of the greatest bands on earth? I mean, this is just my opinion and I think I am allowed to have it.
Third, I am not trying to split hairs, but I happen to love Hemispheres, even though I love albums like Fly By Night, Caress of Steel, 2112 and A Farewell To Kings, just a tiny bit more. To regard an album such as Hemispheres, as a serious misstep, is such a bold statement to make, if you ask me, but hey, that's your opinion and you have every right. You don't see me questioning you about your opinion, do you? So, please be fair and respect my opinions too, no matter how bold (or absurd) they might seem, to you.
