The albums with 'Slave Ship', which is a highly hypnotic piece of music, continuously driving on a simple, repetitive riff and vivid drums. Slowly, subdued screams and vocals are added, often barely audible over this massive wall-of-sound. Especially the clean vocals give the whole an occult, fearsome atmosphere. 'Which House' delves a little deeper into vintage hard rock, which in fact was doom metal altogether. Again driving on monolithic guitars, now a number of soundscape give the music even more of that dark ethos.
That being said, there seem to be some elements from shoegaze here as well, mainly in the haunting soundscapes of the guitars, only much heavier, naturally. 'Kholat Syakhl' (a transliteration in Russian of Holatchahl, meaning "Dead Mountain") is possibly my favorite track. I really dig this primitive, grinding sound and the lingering tempo. I also dig the spooky drone track 'Hal' by the way. Organ should make some more of those haunting instrumentals.
Organ is mainly influenced by bands like Om, Sleep, Electric Wizard and so on and that's quite audible on this album. However, they definitely prove to have their own identity, placing Organ somewhere between those bands and steamrollers like Conan or Yob. My absolute favorite track 'Enuma Anu Enlil' is the proof of that and a brilliant piece of doom metal. So, my fellow doomers, you better check out this album because this is a band we'll hear a lot more from in the near future.
