Sumac's "Love in Shadow" and "The Healer" should be under avant-garde metal

Sumac is very much the continuation of the post-sludge of Aaron Turner's former band Isis, but for these two albums, there are enough experimental aspects to consider them avant-garde metal as well. In a somewhat similar vein to Kayo Dot, the really lengthy tracks have so much going on with occasional usage of unconventional instruments, such as the organ performed by Faith Coloccia. So I'd like to submit Sumac's "Love in Shadow" and "The Healer" to The Hall to be added to avant-garde metal while maintaining their position in post-metal, sludge metal, and those genres' respective clans.
