The "Drought" link is actually a full EP. Kudos for listening to the whole thing.
Believe it or not, DsO started out as raw traditional black metal. In 2004, they released an album called "Si Monumentium Requires Circumspice", which was still very much black metal with more polished recording production and some of the abnormal qualities that more define their sound today. After that album, they went all out avant-garde/prog/blackmetal/whatever.
By the way, Hadron, that song was pretty damn cool. The vocals did remind me of Haken, as well. There were alot of YT comments blabbing about how they didn't like the vocalist, but I had no problems upon listening.
Here is a progressive metal piece for your earvaginas. The sole member of this band, Ron Jarzombek, hammers out some insane guitar work.
Very well composed in my opinion.
