Towards Darkness, formerly known as The Mass, have been active in the underground Canadian doom scene for over a decade now. Under their old name they played a form of sludgy death doom, releasing a full-length album in 2004 before adopting a new style with the name change the following year. They play a melodic form of funeral doom now, with two releases under their belt.
They aren't the exact same melodic funeral doom a la Shape of Despair or Remembrance, but they definitely aren't as extreme as say, Ahab's debut or Esoteric.
As for your questions, Array, I'll definitely make note of the limited release opinion. I'd be curious to know whether they do it for aesthetic purposes, collection purposes, or just to see who the real die-hard fans are. :/
Will make sure to include that as well. I'm assuming given the lack of Canadian doom projects that they look South or across the border for doom influences, although I can't be sure what other music they draw inspiration from.
