OK mate, let me ellucidate.
Morbid Angel - Pre domination - songs were too vague, undirected and a bit boring to be honest. Theres the odd good track, and in terms of influence, I know that theyre very important - however, their music never really hooked me. I prefer the non-David Vincent stuff, and I think that both Formulas and Gateways are amazing albums. I don't like Heretic much though.
Emperor - The big "so what?" of the more accesible black metal albums. Yeah, so they added some parping trumpet samples and warbled on about myths. Their discordant tending to semi-melodic shtick got really tired, really quick. They also couldn't carry a hook in a bucket. I don't like Black Metal much at all, to be honest, and (perhaps tellingly) I would much rather listen to Cradle of Filth from the same period than to Emperor. They have a good tune or two, but I don't see what all the fuss is about. I find them rather dull.
Darkthrone - If I wanted to hear a punk band record in a tin shed next to my house, while someone shrieks rather banal lyrics over the top, I'm sure I could arrange it. Shit production is shit production, necro or not. Punk riffs are punk riffs, not grim tr00ness. I'm rather fond of Darkthrone in their interviews, and I almost get the impression that they are laughing along at everyone buying their half-baked nonsense. Whether in pseudo punk mode or Celtic Frost loving mode, I find them equally yawnsome.
