Controversial lyrics, rowdy stage shows, and push-the-limit vocals have made Slipknot a favorite band for many and drawn the ire of others. Never ones to back down, the group makes no apologies for their sound, lyrics, or videos. Fans love their hard-charging vocals and lyrics that address the darker side of life. Their albums and concerts sell quickly, and many of their fans show up for performances in their favorite Slipknot mask. All band members wear masks ranging from deranged clown faces to a monster straight out of a horror movie. Wear one that you found from a reliable seller on eBay to their next show. Another famous piece of the band's memorabilia is the Slipknot jumpsuit. Whether in red or black, the band members wear them onstage, in appearances, and in videos. Moreover, they are popular with fans for Halloween. Choose one in your size and pair it with the mask for the perfect costume. It’s like music meets theater meets the stuff of nightmares—all in the name of heavy metal.
