Death metal is a subgenre of heavy music, I prefer Progressive Metal though

It emerged in the late 1980s, it was not not commercially successful at first, but it combines many genres like jazz and salsa and fusion rock into one genre!

Salsa music
Salsa music is a popular dance music genre that initially arose in New York City during the 1960s. Salsa is the product of various musical genres including the Afro-Cuban son montuno, guaracha, cha cha chá, mambo, and to a certain extent bolero, and the Puerto Rican bomba and plena. Latin jazz, which was also developed in New York City, has had a significant influence on salsa arrangers, piano guajeos, and instrumental soloists.

Progressive metal
Progressive metal (sometimes known as prog metal) is a fusion genre melding heavy metal and progressive rock that combines the loud "aggression" and amplified guitar-driven sound of the former with the more experimental, cerebral or "pseudo-classical" compositions of the latter.
Whilst the genre emerged towards the late-1980s, it was not until the 1990s that progressive metal achieved commercial success. Queensrÿche, Dream Theater, Tool, Symphony X, Shadow Gallery, Angra, King's X, and Fates Warning are
