Sonic Poison are a band from Finland that plays a mixture of crust, grindcore, thrash and death metal and this is a review of their 2016 ep "Harsh Demonstration" which was released on cassette by Caligari Records.
Spoken word samples start off the ep before going into more of a brutal crust/grindcore direction along with some screaming vocals and you can also hear a lot of 80's thrash and death metal influences in the bands musical style along with some touches of hardcore and crossover as well as a great amount of blast beats.
Morbid sounding melodies can be heard in certain sections of the recording and most of the tracks are very short in length while all of the musical instruments have a very powerful sound to them and the songs stick to a very fast, heavy and raw musical style from beginning to ending of the recording and there is also a brief use of guitar leads.
Sonic Poison plays a musical style that takes the heaviest elements of 80's crust, thrash, grindcore and death metal and mixes them together to create a very heavy sounding recording, the production sounds very old school while the lyrics cover dark and violent themes.
In my opinion Sonic Poison are a very great sounding mixture of thrash, crust, grindcore and death metal and if you are a fan of those musical genres, you should check out this band. RECOMMENDED TRACKS INCLUDE "Repulsive Reactions" "Carbonized" and "Miserable Death". 8 out of 10.
