Very cool!
I'm relatively new to Thy Catafalque. The name kept popping up over the years and for some reason I never got around to checking them (him?) out.
Then I finally tried with Naiv, last year, and I thought it was fantastic. I'm still in "discovery" phase, so it's a bit early for me to rank stuff. Vadak is great too, for sure. Rengeteg and Meta particularly caught my attention. But, again, I haven't even gone through all the albums yet.
One thing that stands out is how their music manages to be catchy and cohesive, despite how varied and out-there it is. Not something that can be said for all "avant-garde" metal (whatever that label means...)
