They are THE best industrail metal bands to come into existence.
They began in Cleveland Ohio, where most fans are located, however, the well-versed metal heads of other areas may be familiar with works such as:
Destroy The World Around Me
Born Of Desire
These Filthy Hands
Nowhere to Go
...and the list goes on
They are commonly called a Slipknot knockoff by ignorant losers who like shitty metal like Linkin Park and who are too lazy to actually visit the bands website and see that Mushroomhead was formed almost 5 years before Slipknot, had a more theatrical concert compilation and performance than Slipknot and continued writing songs that would please their fans, rather than try to get radio time like Slipknot. They are an amazing band any self-respecting metal head should listen to.
