I don't give a shit about radio band fans and what is popular. I'm talking about Metal Church's peers showing some respect/recognition to one of their own.
I know, but it's not about who YOU and I think are significant.
It's about who THEY might think are significant enough to send condolences.
I think it's clear that these metal musicians are more likely send them out when the associated band is really large or:
1. They are friends with them/have toured with them in the past
2. They really like their music and/or were influenced by them
2nd era MC doesn't fit the bill for these.
In short, they don't think MC is their peer or "one of their own" as they made it much further than MC did and don't send out condolences to far less known bands (except with the rare exception of Exodus/Nasty Savage for the odd drummer/cancer connection).
It is odd that musicians that toured with MC at the time (Judas Priest, Alice Cooper) have said nothing. Jason McMaster from Dangerous Toys did though, which makes sense.
I could make a giant list of metal musicians who died who got no shout-out from any of the bands mentioned here.
Come to think of it, I remember very little being said when David Wayne died, even from the remaining members of MC themselves or all the bands that toured with them at the time.
