Geist are a band from Columbus, Missouri that plays a very technical, progressive and melodic form of black/death metal and this is a review of the 2 tracks that they have post on their Reverbnation page.
The first tack "The Dark Core" starts out with a very heavy and progressive sound along with growing up a bit and then slowing down and adding in a mixture of black and death vocals as well as all of the musical instruments sounding very powerful and then clean guitars are added into the song before returning back to a heavier direction and melody is added into the guitar riffing.
The second track "Aeolipile" starts off with fore adding in vocals which are in the more blackened death metal vein and when they add in leads they bring in a 70's metal feeling and after awhile the riffing gets more technical and towards the end melodic vocals are added into the song.
With these 2 songs Geist show a great amount of talent and skill with the way they mix melodic and progressive black metal with the more mid paced technical style of death metal along with a powerful and professional sounding production as well as some dark lyrics.
In my opinion Geist are a very great sounding melodic, progressive and technical black/death metal band and if you are a fan of this musical genre, you should check out their music. 8 out of 10. http://www.reverbnation.com/geistmetal#
