Background: Popol Vuh (also Popol Wuj) is a cultural narrative that recounts the mythology and history of the K'iche' people who inhabit the Guatemalan Highlands northwest of present-day Guatemala City. The Popol Vuh is a creation narrative written by the K'iche' people before the Spanish conquest of Guatemala, originally preserved through oral tradition until approximately 1550 when it was written down. The survival of the Popol Vuh is credited to the 18th century Dominican friar Francisco Ximenez who made a copy of the original text in Spanish The name "Popol Vuh" translates as "Book of the Community", "Book of Counsel", or more literally as "Book of the People". The Popol Vuh includes the Mayan creation myth, beginning with the exploits of the Hero Twins Hunahpu and Xbalanque.
Context: Since its rediscovery by Europeans in the 19th century, the Popol Vuh has attracted the attention of many authors. For example, the myths and legends included in Louis L'Amour's novel The Haunted Mesa are largely based on the Popol Vuh. The planet of Camazotz in Madeleine L'Engle's A Wrinkle in Time is named for the bat-god of the hero-twins story. The text was also used by German film director Werner Herzog as extensive narration for the first chapter of his movie Fata Morgana (released 1972). Mexican painter Diego Rivera did a series of watercolors in 1931, as illustrations for the book.  In 1934, the Franco-American early avant-garde composer Edgard Varese wrote his Ecuatorial - a setting of words from the Popol Vuh for bass soloist and various instruments. The Argentinian composer Alberto Ginastera began writing his opus 44 symphonic work Popol Vuh in 1975, but left the work incomplete at his death in 1983.  In Munich, Germany in 1969, keyboardist Florian Fricke--at the time ensconced in Mayan myth--formed a band named Popol Vuh with synth player Frank Fiedler and percussionist Holger Trulzsch. Their 1970 debut album, Affenstunde, reflected this spiritual connection. The band is notable especially for its extremely early experimentation with forms that became popularized through the modern electronic, new age/ambient music that was to follow years later. They also worked together with Werner Herzog for 5 of his movies. Another band by the same name, this one of Norwegian descent, formed around the same time, its name also inspired by the K'iche' writings.

Background: Slipknot is an American heavy metal band from Des Moines, Iowa. The band was formed in 1992 by percussionist Shawn Crahan, drummer Joey Jordison and bassist Paul Gray. After several lineup changes in its early years, the band settled on nine members for more than a decade: Corey Taylor, Mick Thomson, Jim Root, Paul Gray, Craig Jones, Sid Wilson, Shawn Crahan, Chris Fehn and Joey Jordison. Gray died on May 24, 2010, and was replaced during 2011-2014 by guitarist Donnie Steele.
Context: The band is known for its attention-grabbing image; the members perform wearing unique, individual facemasks and matching uniforms--typically jumpsuits--while each member is typically assigned and referred to by number based on their role in the band (#0 through #8), although the latter practice has diminished following the death of Paul Gray.  The band has said the idea of wearing masks stemmed from a clown mask that Crahan took to rehearsals when the band first started. Crahan later became known for his clown masks, adopting the pseudonym "Shawn the Clown". The concept developed; by late 1997, the band decided every band member would wear a unique mask and matching jumpsuit. Taylor said in 2002, "it's our way of becoming more intimate with the music. It's a way for us to become unconscious of who we are and what we do outside of music. It's a way for us to kind of crawl inside it and be able to use it." The concept of wearing matching jumpsuits has been described as a response to commercialism in the music industry and led to the idea of assigning the band members numerical aliases. According to Taylor, "Originally, we were just going to wear the jumpsuits ...  we figured we might as well take that further and number ourselves ...  We were basically saying, 'Hey, we're a product!'".  During their careers, the members of Slipknot have developed their images, updating their uniforms and each member's mask upon the release of each album. The appearance and style of the masks do not usually differ significantly between albums; members typically maintain the established theme of their mask while adding new elements. Jordison, in an interview in 2004, said the masks are updated to show growth within each individual. Slipknot's members have worn special masks for specific occasions, most notably for the music video and live performances of "Vermilion" in 2004 and 2005 when they wore life masks made from casts of their own faces. In 2008, the band wore a set of large masks titled "purgatory masks" during photograph shoots before the release of All Hope Is Gone; in the music video for "Psychosocial" they are seen burning them. Shortly after its inception, Slipknot's masks were homemade, but since 2000 they have been custom-made by special effect artist and musician Screaming Mad George.  The band's image has been the subject of much criticism and controversy, with critics generally accusing it of being a sales gimmick. The band's members object to these claims; according to them the masks are used to divert attention from themselves and put it on the music. Several band members have said wearing the masks helps to maintain privacy in their personal lives. During an interview in 2005, percussionist Fehn said the masks were a "blessing" because they meant the members are not recognized in public. In 2012, Slipknot released an app for iOS and Android called "Slipknot: Wear the Mask", which invites fans to construct their own masks, defining the kind of Slipknot fans they are.
Question: How did they respond to that accusation?

The band's members object to these claims; according to them the masks are used to divert attention from themselves and put it on the music.
