Similar to their previous releases, heavy metal environmentalists Earth Crisis combine brutal music with thought-provoking lyrics on Breed the Killer. The only problem is, without the aid of a lyric sheet, you have to take their word for it, since the vocals are a combination of unintelligible barks and growls. Their musical approach can be compared to such other politically oriented bands as Rage Against the Machine and Sepultura, but Earth Crisis' compositions contain more prominent elements of hardcore than the aforementioned outfits. For example, "Ultramilitance" is an anthem for eco-terrorists, inspired by those who put an end to whaling ships and fur factories. Heavy riffs and drumming can be found throughout the entire album -- the opening "End Begins," "Drug Related Homicide," "Filthy Hands to Famished Mouths," and the title track are all prime examples. It may sound a bit monotonous to the uninitiated, but longtime fans will surely be pleased.
