Continuum's
Continuum II is what your looking for. They are not on the archives, and they seem generally unkown to metal fans (this probably has to do with the fact that they are largely considered ambient due to their debut). But
Continuum II is most definitely a drone doom album.
The album consists of three tracks. The first one is mainly why Im throwing this rec at you. Its a 20+ minute, heavy as hell, slowly evolving guitar drone. Its as heavy as any other drone doom, yet the guitar is given much more room to breathe. This allows the guitar to really drive its riffs home. There is some ambience in the begining, but its simply there as an intro. This is probably one of the best drone doom songs I have ever heard, and its made by an artist not even known in the drone doom community.
The next two songs are less along the lines of what your looking for, but the variety of this album is what makes it stand out from other drone. The second song is a very srange and creepy ambient song, with guitar feedback and whispered vocals intertwined. The third and final song is a combination of the first two. The guitars don't really form riffs as they did in the first song, rather they ...well, drone on, spewing feedback everywhere. Much more so than the secomd track. Ambiance builds under the feedback, and eventually the guitars become so strong, that everything just disintigrates and collapses on itself at the end.
But really, if nothing else, you should hear the first track. Since they are not on MA, you can find an album page here:
