Ontologus were previously called Requiem, and well, Requiem seems like it would have been a pretty common name for a band, in fact there were three in India alone according to Reverbnation search. So I guess it's a good thing they changed their name. Their Reverbnation profile says Progressive Metal/ Extreme. But they're definitely not prog. And Extreme is just a general term. I'd say they're closer to Melodeath than anything else. But apparently they're "...a bunch of serious musicians who don’t take themselves seriously". So, I'm sure that's explains everything clearly.
