To Bob's assertion of diversity, I submit the 2005 lineup of Maryland Deathfest: You've got the gore-infused Carcass style of death metal purveyed by bands like Lord Gore, Impaled and General Surgery, grindcore stalwarts Pig Destroyer, Regurgitate, Birdflesh, and Leng T'che, blasphemic legends Immolation, brutal death metal legends Cryptopsy, brutal death up-and-comers Wormed, and DIY workhorses like Magrudergrind waiting to pick up the pieces.
Now, in light of this, I'd think the casual death metal listener has heard of maybe four or five of these bands, and given a serious listen to maybe two or three. This is only about half the bands at that festival (other names not mentioned: Warscars, Guttural Secrete, XXX Maniak, Kill the Client, Despised Icon, Ion Dissonance, Amoebic Dysentery, etc. etc). Just understand that what you think is a nuance sense of "diversity" isn't really diversity.
But I'm not clamoring for utmost diversity here; it wouldn't be Ragnarokkr if they started lining the roster with death metal bands or something like that. And I don't want it to be Chicago Powerfest either. I'm just saying that given a lineup that has 30-40 bands, 25 or more of which I've never even heard of (yet, somehow I have an idea of how they'll sound based on stereotypes and genre tropes), I'm not as excited to delve into it.
Plus the band name Dogbane just sucks. And I'm not listening to a band with that name.
