Any suggestions for bands similar to my all time favourite Black Crown Initiate?

Heya Morbid Angel 13. Here are some recs of prog death for you. I'd say most of those also incorporate tech death or exerimental and avantgarde stuff.

1. Fleshvessel
2. Deviant Process
3. An Abstract Illusion
4. Obsidious
5. First Fragment
6. The Ritual Aura
7. Alkaloid
8. Beyond Creation
9. Sarmat
10. Sleep Terror

If you ever want more rec of the sort here's a list of mine that could potentially help you and incorporate albums as well.

Hope this can help you out!

I would start with the 90'ties and recommend Pan.Thy.Monium, Atheist, Edge of Sanity and Gorguts.
