This puts Slipknot to shame. A heavy metal band with great lyrics. The music is so powerful. J. Mann's growl will bring you back for more. Jeffrey Nothings voice burns his lyrics into your brain. The music is very catchy and great sound. Has great bass lines that go along great with the keyboard and samples. They have done something right with there music. They are truly an awesome band. Be sure to catch them on Ozzfest 2002 and you will be a fan. They are truly hardcore.
