Ministry

Ministry popularized industrial-metal by injecting large doses of punky, over-the-top aggression and roaring heavy metal guitar riffs that helped their music find favor with metal and alternative audiences outside of industrial's cult fan base. That's not to say Ministry had a commercial or generally accessible sound: they were unremittingly intense, abrasive, pounding, and repetitive, and not always guitar-oriented (samples, synthesizers, and tape effects were a primary focus just as often as guitars and distorted vocals).
