Heidenreich where a band from Austria that had members of Abigor and they played a style that I would describe as being avant garde metal and this is a review of their 1997 album "Trance Of An Unholy Union" which was released by Napalm Records.
Drum programming is a mixture of slow, mid paced, and fast beats, while the Synthesizers are very symphonic and avant garde sounding with a small amount of piano that gives the music a horror movie soundtrack feel, as for the bass playing it follows the riffs that are coming out of the guitars.
Rhythm guitars are a mixture of slow and fast black metal riffing that is more primal than most avant garde black metal and they also contain a good amount of melody, while the lead guitars have a very weird and distorted sound with some melodic guitar solos.
Vocals are mostly high pitched black metal screams with some clean singing being used at times with some spoken word passages, while the lyrics touch on the occult,satanic, and cosmic themes, as for the production on this album which was recorded and mixed at Tonstudio Hoernix during 1997 sounds very professional and you can hear all of the instruments that are present on this album.
In my opinion Heidenreich where a very underrated avant garde black metal band for their time and if you are a fan of this style you should check out this band. RECOMMENDED TRACKS INCLUDE "Cosmic Reflections" "Grim and Bitter Heart" and "Trance Of An Unholy Union". RECOMMENDED BUY.
