Mantas was the late Chuck Schuliner’s pre-Death band and these are his earliest recordings; ones that would evolve into Death’s sound. As such, Death By Metal should be considered to be a historical metal document. This said, the album’s sound is incredibly muddy and as a result hard to listen to at times. While most casual listeners won’t be able to get past this, those who can will find some scorching songs. As far as historical albums go, Death By Metal should be heard by all extreme metal fans at some point, just to see how the genre evolved. Casual listeners on the other hand should avoid.
