IN: 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.

Anticipation for Slipknot's second album was intense. In early 2001, the band began recording the second album at Sound City and Sound Image studios in Los Angeles. Around this time, conflicts arose between band members due to extensive touring and recording schedules. Recording of their second album ended in February 2001 and the band embarked on their Iowa World Tour. Entitled Iowa, Slipknot's second album - released on August 28, 2001 - peaked at number three on the Billboard charts and at number one in the UK. The album produced three singles; "The Heretic Anthem" (promotional single), "Left Behind", and "My Plague", which appeared on the soundtrack for the film Resident Evil. In 2002, Slipknot appeared in Rollerball (2002), performing "I Am Hated". The release and intense promotion of the album resulted in sold-out shows in large arenas in several countries.  In mid-2002, Slipknot went on hiatus because of internal conflicts, and band members focused on side projects. Vocalist Taylor and guitarist Root revived their band Stone Sour, drummer Jordison created Murderdolls with vocalist Wednesday 13, percussionist Crahan founded To My Surprise and DJ Wilson went solo as DJ Starscream. For a while, the future of Slipknot was uncertain and there was much speculation about whether there would be a third album, or if the split would become permanent. "I don't have a problem with anyone in Slipknot," Jordison protested. "I've seen comments from Corey saying there are things to be resolved, but I have no fucking idea what he's talking about."  Nonetheless, on November 22, 2002, Slipknot released their second DVD, Disasterpieces.

IN: Lillian Evelyn Moller Gilbreth (May 24, 1878 - January 2, 1972) was an American psychologist, industrial engineer, consultant, and educator who was an early pioneer in applying psychology to time-and-motion studies. She was described in the 1940s as "a genius in the art of living." Gilbreth, one of the first female engineers to earn a Ph.D., is considered to be the first industrial/organizational psychologist.

For more than forty years, Gilbreth's career combined psychology with the study of scientific management and engineering. She also included her perspectives as a wife and mother in her research, writing, and consulting work. Gilbreth became a pioneer in what is now known as Industrial and organizational psychology. She helped industrial engineers recognized the importance of the psychological dimensions of work. In addition, she became the first American engineer ever to create a synthesis of psychology and scientific management. (Gilbreth introduced the concept of using psychology to study management at the Dartmouth College Conference on Scientific Management in 1911.)  In addition to jointly running Gilbreth Incorporated, their business and engineering consulting firm, Lillian and Frank wrote numerous publications as sole authors, as well as co-authoring multiple books and more than fifty papers on a variety of scientific topics. However, in their joint publications Lillian was not always named as a co-author, possibly due to publishers' concerns about a female writer. Althhough her credentials included a doctorate in psychology, she is less frequently credited in their joing publications than her husband, who did not attend college.  The Gilbreths were certain that the revolutionary ideas of Frederick Winslow Taylor would be neither easy to implement nor sufficient; their implementation would require hard work by engineers and psychologists to make them successful. The Gilbreths also believed that scientific management as formulated by Taylor fell short when it came to managing the human element on the shop floor. The Gilbreths helped formulate a constructive critique of Taylorism; this critique had the support of other successful managers.

IN: Social Distortion is an American punk rock band formed in 1978 in Fullerton, California. The band currently consists of Mike Ness (lead vocals, lead guitar), Jonny Wickersham (rhythm guitar, backing vocals), Brent Harding (bass, backing vocals), David Hidalgo Jr. (drums), and David Kalish (keyboards). Social Distortion went on a temporary hiatus in the mid-1980s, due to Ness' drug addiction and troubles with the law which resulted in extended stints in various rehabilitation centers that lasted for two years. Since its inception, the band lineup has been a virtual revolving-door of talent with many members coming and going - Ness has been the only constant member.

After the release of Prison Bound, Social Distortion left Restless Records and signed with Epic. The band then returned to the studio around the summer/fall of 1989, with producer Dave Jerden, to begin recording their self-titled third album, which was released in 1990. It was Social Distortion's first album that was not financed by the band. The album includes the singles "Ball and Chain" and Story of My Life as well as a cover of Johnny Cash's Ring of Fire. The self-titled album fared better than both Mommy's Little Monster and Prison Bound, and is often credited as Social Distortion's best known work, with sales continuing 28 years after its release. It is also sometimes cited as among the best rock albums of 1990--the album is said to "split the difference between rockabilly and Ramones-style punk."  The fourth album, Somewhere Between Heaven and Hell, was released in 1992. The album included two hit singles--"Bad Luck", and "When She Begins". Somewhere Between Heaven and Hell surpassed all their previous albums in popularity. The album has a similar sound to the previous, eponymous, album, said to be a blend of "punk, blues, country and rockabilly". After the release of this album, drummer Christopher Reece left Social Distortion in 1994 and was replaced by Randy Carr. Carr toured with the band and played drums on live performances until he left in 1995.  The band took another hiatus after the release of Somewhere Between Heaven and Hell, and did not return to the studio until 1995. During the break, Social Distortion released a compilation album, Mainliner: Wreckage From the Past (1995), featuring pre-Mommy's Little Monster cuts. It contains two versions of "1945" and "Playpen" from their two indie labels, 13th Floor, and Posh Boy, and also a cover of the Rolling Stones' "Under My Thumb".  In June 1994, the band began demoing songs for the fifth album, then returned to the studio in 1995 to record White Light, White Heat, White Trash, which was released in 1996. The album is said to have taken on a harder sound than those preceding it, and to not focus as much on their previous blues and rockabilly sound. The single "I Was Wrong" received wide radio play and is said to resemble "the classic sound more than any other track on the album". The album also features the singles "When the Angels Sing," which is said to be a tribute to Ness's grandmother, who was an avid supporter of the band, and "Don't Drag Me Down". The album also included a re-recorded version of "Under My Thumb", a cover of the Rolling Stones, as a hidden track. Former Danzig drummer Chuck Biscuits joined the band between the recording and release of the album, and is credited in the liner notes although this album actually features one time Journey drummer Deen Castronovo. White Light, White Heat, White Trash was the final Social Distortion album recorded with Dennis Danell before his death.
