PROBLEM: Passage: Dark Heresy is considered a progressive death metal band. Dark Heresy's 1993 demo Diabolus in Musica was praised for amalgamating "well-chosen sprinklings of classic Morbid Angel with a UK death [metal] flair", and for mixing thrash "with classy chunks of unapologetic metal." Although dismissed by rock music magazine Kerrang! as "a widdly Carcass", their 1995 album Abstract Principles Taken to Their Logical Extremes was praised by extreme music magazine Terrorizer, who wrote that "Dark Heresy's music is not about mind-numbing brutality and dazzling speed, but is about complex and reflective musical structures supporting complex ideas ... while the vocals swing from gruff grunts to choral chants", and described Diabolus In Musica as "one of the most inventive works from an occultist band." Writing in Isten magazine in 1996, Endre Begby described Dark Heresy as "speak[ing] a tonal language very uncommon in death metal" and "break[ing] out of the fifth and major/minor third patterns." He similarly compared part of Abstract Principles Taken to Their Logical Extremes to Morbid Angel's 1989 debut album Altars of Madness, while noting that other parts are "totally flipped out, finding no comparison in modern metal", and summing up that Dark Heresy "fuck with the very foundation of death metal as we know it". Heavy metal and hard rock website Worshipmetal.com agreed with these assessments when revisiting Abstract Principles Taken to Their Logical Extremes in 2017, noting the complex compositions, and adding that Dark Heresy "seemed to throw every single idea into the mix, culminating in a bewildering experience that managed to be both beautiful and brutal in the same breath", and finding similarities between Dark Heresy's music and that of Carcass, Pestilence, and the Mahavishnu Orchestra, and describing their approach to songwriting as "difficult to pin down but ... utterly unique nonetheless."

PROBLEM: Passage: The Yardbirds are an English blues rock band from London. Formed in May 1963, the group originally included lead vocalist Keith Relf, lead guitarist Anthony "Top" Topham, rhythm guitarist Chris Dreja, bassist Paul Samwell-Smith and drummer Jim McCarty. In October, Topham was replaced by Eric Clapton. He remained until 13 March 1965, when he left due to creative disagreements. Clapton recommended Jimmy Page to replace him, but he declined and Jeff Beck took over. Page later joined on bass the following June, after Samwell-Smith abruptly quit; Dreja later took over the role, allowing Page to join Beck on guitar. This lineup was short-lived, however, as Beck left in November 1966. The group continued as a four-piece until July 1968, when Relf and McCarty left due to creative differences, primarily with Page. Dreja initially remained, but by August Page formed a new group with vocalist Robert Plant, bassist John Paul Jones and drummer John Bonham, who later renamed themselves Led Zeppelin.

PROBLEM: Passage: In August 1991, hard-line Communists launched a coup against Gorbachev; while the coup quickly fell apart, it broke the remaining power of Gorbachev and the central Soviet government. Later that month, Gorbachev resigned as general secretary of the Communist party, and Russian president Boris Yeltsin ordered the seizure of Soviet property. Gorbachev clung to power as the President of the Soviet Union until December 1991, when the Soviet Union dissolved. Fifteen states emerged from the Soviet Union, and of those states, Russia was the largest and most populous. Bush and Yeltsin met in February 1992, declaring a new era of "friendship and partnership". In January 1993, Bush and Yeltsin agreed to START II, which provided for further nuclear arms reductions on top of the original START treaty. The collapse of the Soviet Union prompted reflections on the future of the world following the end of the Cold War; one political scientist, Francis Fukuyama, speculated that humanity had reached the "end of history" in that liberal, capitalist democracy had permanently triumphed over Communism and fascism. Meanwhile, the collapse of the Soviet Union and other Communist governments led to post-Soviet conflicts in Central Europe, Eastern Europe, Central Asia, and Africa that would continue long after Bush left office.
