Marrow was a poop. A smelly poop. Agalloch could have released anything at that time and it would have been acclaimed, 2010 was just their time to break through.
The Tenant by Ludicra deserved every fucking ounce of success, both critically and commercially, that Marrow received back in 2010. So, so, so sad. That will probably go down as one of the great tragedies of modern underground metal in the years to come I think.
