A British band who, in the 80s and then the 90s, helped to start and then define grindcore music. They are still generally regarded as the genres primogenitors. Grind is basically short and fast, with very sludgy guitars and bass and shouty/growly vocals. Short in the extreme sense - Napalm Death's best known record, 1987's Scum, contained 28 tracks in 33 minutes, the longest being just over 2 minutes, and the shortest being 4 seconds. Because of these aspects, grind has obviously never really gotten through to the mainstream. Napalm Death are still going today (Feb 2004).
An awe-inspiring death metal band from Canada. Not brand new, but also not long-standing scene members, the band's sound is so full-on and complete that they have even invented a name for their style - Northern Hyperblast. They have never attained such recognition as (for example) fellow Canadians Cryptopsy, but the quality of albums such as In Shadows and Dust and The Prophecy suggest that maybe they should have.
