Reply #20: Usually the blast beats are the most noticeable difference.

The term came from the grinding style of guitars mixed with hardcore punk. There's different styles of it, but the songs are usually short and aggressive, and have pretty hateful vocals. Agoraphobic Nosebleed did a CD called Frozen Corpse Stuffed With Dope that had 99 songs in 20 minutes. One review called it the "Paul's Boutique" of grindcore. Repulsion and Heresy were real early examples of the genre, but Napalm Death really put the genre on the map. Pig Destroyer is easily my favorite of the bunch. Their last CD, Phantom Limb, is the best example of current day grindcore, imo.

Suicidal's first album was almost pure punk. By Join The Army there was starting to get more metal. I liked all of it. :)
