Subgenre of metal that is mostly characterized by heavier detuned riffing and complex rhythmic compositions diversifying itself outside the blast beat ridden thrash metal predecessors. Vocals changed over from the raspy throaty vocals of thrash to gutteral roars. Early influences include Hellhammer/Celtic Frost and Death (considered one of the first death metal bands). Later death metal bands incorporated detuning from standard tuning (for their guitars and bass guitars) for a heavier sound as well as influences from jazz/fusion for multiple time signature changes, start and stop tempo changes etc.
