if u like circus maximus, check out andromeda. very similar to CM and DT. extremely underrated.
but seriously, i absolutely hated growling for the longest time, just thought it was the most annoying crap ever. Then i checked out between the buried and me and really loved the instrumentals. i honestly just sat there for a few hours listening to it for a few hours until i could tolerate it cause the instrumentals were too good to pass up. You should give it a shot cause its exactly what you are looking for. my 2nd favorite band right now
