Well you have gone a bit backwards, that stuff is generally seen as a gateway into extreme metal. They incorporate the harsh vocals, some blasting and some more aggressive riff work, but it's not as oppressive or violent as most death metal. Obviously you're already used to all that stuff. I never really got into all the other "melodeath" like In Flames, Soilwork, Slaughter of the Soul era At the Gates, etc.
Since you listened to that I think you should revisit Sacramentum's Far Away from the Sun and post your thoughts on it. It's far superior to nearly everything else that came out of Gothenburg imo. The melodies are far more unique rather than aping Iron Maiden and the drumming fucking rules. Also since it's far more rooted in black metal I think the harsh vocals are fitting.
