ABACABB
ABACABB is een deathcore band uit Sterling, Virginia.
"A-B-A-C-A-B-B is input-code which enables the blood/gore effects for the original Mortal Kombat video game. Also, the code was in turn named "Abacabb" because of the Abacab album by the rock band Genesis, and this code was used only on the Sega Genesis version of the game." Bron: The Metal-Archives.com
