Background: Slayer is an American thrash metal band from Huntington Park, California. The band was formed in 1981 by vocalist/bassist Tom Araya and guitarists Kerry King and Jeff Hanneman. Slayer's fast and aggressive musical style made them one of the founding "big four" bands of thrash metal, alongside Metallica, Megadeth and Anthrax. Slayer's current lineup comprises King, Araya, drummer Paul Bostaph and guitarist Gary Holt.
Context: In late 1987, Slayer returned to the studio to record their fourth studio album. To contrast the speed of Reign in Blood, the band consciously decided to slow down the tempos, and incorporate more melodic singing. According to Hanneman, "We knew we couldn't top Reign in Blood, so we had to slow down. We knew whatever we did was gonna be compared to that album, and I remember we actually discussed slowing down. It was weird--we've never done that on an album, before or since." Released in July 1988, South of Heaven received mixed responses from both fans and critics, although it was Slayer's most commercially successful release at the time, debuting at number 57 on the Billboard 200, and their second album to receive gold certification in the United States. Press response to the album was mixed, with AllMusic citing the album as "disturbing and powerful," and Kim Nelly of Rolling Stone calling it "genuinely offensive satanic drivel." King said "that album was my most lackluster performance," although Araya called it a "late bloomer" which eventually grew on people. Slayer returned to the studio in spring 1990 with co-producer Andy Wallace to record its fifth studio album. Following the backlash created by South of Heaven, Slayer returned to the "pounding speed of Reign in Blood, while retaining their newfound melodic sense." Seasons in the Abyss, released on October 25, 1990, was the first Slayer album to be released under Rubin's new Def American label, as he had parted ways with Def Jam owner Russell Simmons over creative differences. The album debuted at number 44 on the Billboard 200, and was certified gold in 1992. The album spawned Slayer's first music video for the album's title track, which was filmed in front of the Giza pyramids in Egypt. Slayer returned as a live act in September 1990 to co-headline the European Clash of the Titans tour with Megadeth, Suicidal Tendencies, and Testament. During the sold out European leg of this tour tickets fetched up to 1,000 Deutschmark ($680 USD) on the black market. With the popularity of American thrash at its peak, the tour was extended to the US beginning in May 1991, with Megadeth, Anthrax and opening act Alice in Chains. The band released a double live album, Decade of Aggression in 1991, to celebrate ten years since their formation. The compilation debuted at number 55 on the Billboard 200. In May 1992, Lombardo quit the band due to conflicts with other members, as well as his desire to be off tour for the birth of his first child. Lombardo formed his own band Grip Inc, with Voodoocult guitarist Waldemar Sorychta, and Slayer recruited former Forbidden drummer Paul Bostaph to take his place. Slayer made its debut appearance with Bostaph at the 1992 Monsters of Rock festival at Castle Donington. Bostaph's first studio effort was a medley of three Exploited songs, "War," "UK '82," and "Disorder," with rapper Ice-T, for the Judgment Night movie soundtrack in 1993.

Background: Herbert Marshall McLuhan (July 21, 1911 - December 31, 1980) was a Canadian professor, philosopher, and public intellectual. His work is one of the cornerstones of the study of media theory. Born in Edmonton, Alberta, McLuhan studied at the University of Manitoba and the University of Cambridge. He began his teaching career as a professor of English at several universities in the U.S. and Canada before moving to the University of Toronto in 1946, where he remained for the rest of his life.
Context: During his years at Saint Louis University (1937-1944), McLuhan worked concurrently on two projects: his doctoral dissertation and the manuscript that was eventually published in 1951 as the book The Mechanical Bride: Folklore of Industrial Man, which included only a representative selection of the materials that McLuhan had prepared for it. McLuhan's 1942 Cambridge University doctoral dissertation surveys the history of the verbal arts (grammar, logic, and rhetoric--collectively known as the trivium) from the time of Cicero down to the time of Thomas Nashe. In his later publications, McLuhan at times uses the Latin concept of the trivium to outline an orderly and systematic picture of certain periods in the history of Western culture. McLuhan suggests that the Middle Ages, for instance, was characterized by the heavy emphasis on the formal study of logic. The key development that led to the Renaissance was not the rediscovery of ancient texts but a shift in emphasis from the formal study of logic to rhetoric and language. Modern life is characterized by the re-emergence of grammar as its most salient feature--a trend McLuhan felt was exemplified by the New Criticism of Richards and Leavis. In The Mechanical Bride, McLuhan turned his attention to analysing and commenting on numerous examples of persuasion in contemporary popular culture. This followed naturally from his earlier work as both dialectic and rhetoric in the classical trivium aimed at persuasion. At this point his focus shifted dramatically, turning inward to study the influence of communication media independent of their content. His famous aphorism "the medium is the message" (elaborated in his 1964 book, Understanding Media: The Extensions of Man) calls attention to this intrinsic effect of communications media. McLuhan also started the journal Explorations with anthropologist Edmund "Ted" Carpenter. In a letter to Walter Ong dated May 31, 1953, McLuhan reported that he had received a two-year grant of $43,000 from the Ford Foundation to carry out a communication project at the University of Toronto involving faculty from different disciplines, which led to the creation of the journal. At a Fordham lecture in 1999, Tom Wolfe suggested that a major under-acknowledged influence on McLuhan's work is the Jesuit philosopher Pierre Teilhard de Chardin whose ideas anticipated those of McLuhan, especially the evolution of the human mind into the "noosphere". In fact, McLuhan warns against outright dismissing or whole-heartedly accepting de Chardin's observations early on in his first published book The Mechanical Bride (p. 32): "This externalization of our senses creates what de Chardin calls the 'noosphere' or a technological brain for the world. Instead of tending towards a vast Alexandrian library the world has become a computer, an electronic brain, exactly as in an infantile piece of science fiction. And as our senses have gone outside us, Big Brother goes inside. So, unless aware of this dynamic, we shall at once move into a phase of panic terrors, exactly befitting a small world of tribal drums, total interdependence, and super-imposed co-existence."
