Spheres is the fourth album by Dutch death metal band Pestilence, released in 1993. It was their final album before a 14-year hiatus from 1994 to 2008. On this album, the band experimented with a more progressive sound, utilizing guitar synthesizers as well as some jazz influences. Despite initial mixed reactions due to its experimental nature, Spheres has since been recognized as a pioneering effort in the progressive death metal genre. Decibel rated it positively, appreciating the "ear-candy at every turn" and the superb basswork.
