I know some tech death, too. Although this is mostly just guitar wankery of a series of difficult blast patterns.
And dare I even mention the most generic black metal band?
I do because they're actually amazing at what they do.
I absolutely love the lyrics on that Dark Funeral song.. All their lyrics are amazing, despite their extreme shallowness.
But that's part of the charm, I guess.
Though the lyrics on their last album seem to have a lot more meaning behind them for most of the part. It's less about flat out Satanism and blasphemy and stuff, and it's more indirect. Though there's still a lot of Satanic-tinted stuff there.
And then some blackened death metal for balance. They're christian!
On a lighter note, good speed metal, though this song in particular isn't that fast, aside from the shredding.
