Welterwerk is not "unblack metal" (gay term). It's technical black metal/death metal (black metal really CAN'T be technical, but it's close enough as Abgott is).
I think Abigors latest was very progressive and technical. I have however only listened to it once. I liked it but havent had time to go deeper into it but you should check it out.
