I do not see how Therion is a better swedish DM band then Edge of Sanity. . "Best Swedish DM band", not I REALLY LIKE BEYOND SANCTORUM!!!.
Therion is nothing more than garbage.
and even thought Dissection's one of the greatest metal bands of all time, i wouldn't consider them to be a death metal band.
I would not consider Dissection a DM band, but like say Unanimated they resemble 80's metal and 1st wave BM, not many 90's bands do who play extreme metal.
