I feel like it's the logical conclusion of part of Sabbath's catalog -- ONE BRANCH. Sabbath is amazing because one or two songs contain the seeds for entire subgenre of metal ... and another song, a completely different subgenre. They were around before metal split into thrash, doom, stoner, etc. obviously.
The band "Thou" IMO is the best candidate for heirs to Sabbath, in that they are super literate. They have a specific doom/black metal sound, but borrow a lot from outside of metal.
