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: Have there been criticisms of the way Slipknot presents itself?
Answer: critics generally accusing it of being a sales gimmick.

Background: Frank Lloyd Wright (born Frank Lincoln Wright, June 8, 1867 - April 9, 1959) was an American architect, interior designer, writer and educator, who designed more than 1,000 structures, 532 of which were completed. Wright believed in designing structures that were in harmony with humanity and its environment, a philosophy he called organic architecture. This philosophy was best exemplified by Fallingwater (1935), which has been called "the best all-time work of American architecture". His creative period spanned more than 70 years.
Context: By 1901, Wright had completed about 50 projects, including many houses in Oak Park. As his son John Lloyd Wright wrote:  "William Eugene Drummond, Francis Barry Byrne, Walter Burley Griffin, Albert Chase McArthur, Marion Mahony, Isabel Roberts and George Willis were the draftsmen. Five men, two women. They wore flowing ties, and smocks suitable to the realm. The men wore their hair like Papa, all except Albert, he didn't have enough hair. They worshiped Papa! Papa liked them! I know that each one of them was then making valuable contributions to the pioneering of the modern American architecture for which my father gets the full glory, headaches and recognition today!"  Between 1900 and 1901, Frank Lloyd Wright completed four houses which have since been identified as the onset of the "Prairie style". Two, the Hickox and Bradley Houses, were the last transitional step between Wright's early designs and the Prairie creations. Meanwhile, the Thomas House and Willits House received recognition as the first mature examples of the new style. At the same time, Wright gave his new ideas for the American house widespread awareness through two publications in the Ladies' Home Journal. The articles were in response to an invitation from the president of Curtis Publishing Company, Edward Bok, as part of a project to improve modern house design. "A Home in a Prairie Town" and "A Small House with Lots of Room in it" appeared respectively in the February and July 1901 issues of the journal. Although neither of the affordable house plans was ever constructed, Wright received increased requests for similar designs in following years. Wright came to Buffalo and designed homes for three of the company's executives including the Darwin D. Martin House in 1904.  Other Wright houses considered to be masterpieces of the Prairie Style are the Frederick Robie House in Chicago and the Avery and Queene Coonley House in Riverside, Illinois. The Robie House, with its soaring, cantilevered roof lines, supported by a 110-foot-long (34 m) channel of steel, is the most dramatic. Its living and dining areas form virtually one uninterrupted space. With this and other buildings, included in the publication of the Wasmuth Portfolio (1910), Wright's work became known to European architects and had a profound influence on them after World War I. It is sometimes called the "cornerstone of modernism".  Wright's residential designs of this era were known as "prairie houses" because the designs complemented the land around Chicago. Prairie style houses often have a combination of these features: One or two-stories with one-story projections, an open floor plan, low-pitched roofs with broad overhanging eaves, strong horizontal lines, ribbons of windows (often casements), a prominent central chimney, built-in stylized cabinetry, and a wide use of natural materials--especially stone and wood.
