Background: Pendulum is an Australian drum and bass and electronic rock band founded in 2002. Pendulum originally formed in the city of Perth, Western Australia by Rob Swire, Gareth McGrillen, and Paul "El Hornet" Harding. The band was later expanded to include members, Ben Mount, Peredur ap Gwynedd, and KJ Sawka. Members Swire and McGrillen also formed the electro house duo Knife Party.
Context: When Pendulum was formed, their musical style was considerably more drum and bass sounding than the work they were known for later in their career. Signature tunes such as "Masochist", "Vault", "Back 2 You" and "Voyager", which were released on labels such as Uprising Records, 31 Records, Renegade Hardware and Low Profile Records, have a darker, more amelodic air to them which is substantially absent from their later productions. The band's newer work is regarded as generally leaning heavily towards a mainstream, dance-driven sound. Early work such as "Another Planet" seems to indicate an early affinity with a more global sound, similar to other Breakbeat Kaos artists such as DJ Fresh and Adam F.  The group has produced various remixes of other artists also; one of the best-known being the remix of "Voodoo People", originally by The Prodigy. In 2008-2010, they covered/remixed songs including Led Zeppelin's "Immigrant Song", Linkin Park's "The Catalyst", Calvin Harris's "I'm Not Alone", Coldplay's "Violet Hill", and Metallica's "Master of Puppets". Pendulum's versions of "I'm Not Alone" and "Master Of Puppets" both exist as studio recordings but have not been officially released, and are only previewed during DJ sets. The original live version of "Master of Puppets" was played as an instrumental introduction for "Slam", and was featured on their first live album/DVD. During their American tour as the supporting band for Linkin Park, the song was played in its entirety, with Rob doing vocals. Pendulum have also remixed their own music and, on occasion, television theme songs, such as Australian television's "ABC News Theme" in May 2010. The remix proved to be immensely popular with listeners of Australian youth radio station Triple J, polling at number 11 in the 2010 Triple J Hottest 100 countdown.  Pendulum's musical style consisted of a fusion of drum and bass (along with other electronic genres), alternative rock and heavy metal, with the inclusion of acoustic instruments. This creates a sound reminiscent of electronic rock, albeit with much more prominent drum and bass and, more recently, dubstep influences. Some songs, such as "Slam", "Propane Nightmares" and "Witchcraft" are synth-led, whilst others, such as "Showdown", "The Tempest" and "Comprachicos", are guitar-led. Bassist Gareth McGrillen stated in an interview on Channel 4 that they use 13 computers during the live performances, all of which are mixing the sounds produced by the instruments in real time. Rob Swire stated in issues of TJECK magazine and Rock Sound magazine that he would like to begin producing songs with a punk style to them, which Gareth clarified to mean "A raw, aggressive, less polished method of producing". Pendulum were known to be fans of progressive rock and progressive metal bands, which may have inspired them to fuse multiple genres of music together, which is standard practice in those genres.

Background: Dame Helen Lydia Mirren,  (nee Mironoff; born 26 July 1945) is an English actor. Mirren began her acting career with the Royal Shakespeare Company in 1967, and is one of the few performers who have achieved the Triple Crown of Acting. She won the Academy Award for Best Actress in 2007 for her performance as Queen Elizabeth II in The Queen and received the Olivier Award for Best Actress and Tony Award for Best Actress in a Play for the same role in The Audience. Mirren's other Academy Award nominations include The Madness of King George (1994), Gosford Park (2001) and The Last Station (2009).
Context: In 2015, Mirren reunited with her former assistant Simon Curtis on Woman in Gold, co-starring Ryan Reynolds. The film was based on the true story of Jewish refugee Maria Altmann, who, together with her young lawyer Randy Schoenberg, fought the Austrian government to be reunited with Gustav Klimt's painting of her aunt, the famous Portrait of Adele Bloch-Bauer I. The film received mixed reviews from critics, although Mirren and Reynold's performances were widely praised. A commercial success, Woman in Gold became one of the highest-grossing specialty films of the year. The same year, Mirren appeared in Gavin Hood's thriller Eye in the Sky (2015), in which she played as a military intelligence officer who leads a secret drone mission to capture a terrorist group living in Nairobi, Kenya. Mirren last film that year was Jay Roach's biographical drama Trumbo, co-starring Bryan Cranston and Diane Lane. The actress played Hedda Hopper, the famous actress and gossip columnist, in the film, which received generally positive reviews from critics and garnered her a 14th Golden Globe nomination.  Mirren's only film of 2016 was Collateral Beauty, directed by David Frankel. Co-Starring Will Smith, Keira Knightley, and Kate Winslet, the ensemble drama follows a man who copes with his daughter's death by writing letters to time, death, and love. The film earned largely negative reviews from critics, who called it "well-meaning but fundamentally flawed." In 2017, Mirren narrated Cries from Syria, a documentary film about the Syrian Civil War, directed by Evgeny Afineevsky. Also that year, she made an uncredited cameo appearance in F. Gary Gray's The Fate of the Furious, the eighth installment in The Fast and the Furious franchise, playing Magdalene, the mother of Owen and Deckard Shaw. Mirren had a larger role in director Paolo Virzi's English-language debut The Leisure Seeker, based on the 2009 novel of the same name. On set, she was reunited with Donald Sutherland with whom she had not worked again since Bethune: The Making of a Hero (1990), portraying a terminally ill couple who escape from their retirement home and take one last cross-country adventure in a vintage van. At the 75th awards ceremony, Mirren received her 15th Golden Globe nomination.  In 2018, Mirren portrayed heiress Sarah Winchester in the supernatural horror film Winchester: The House That Ghosts Built, directed by The Spierig Brothers. She will also play Mother Ginger in Lasse Hallstrom and Disney's adaptation of The Nutcracker, titled The Nutcracker and the Four Realms, and is expected to appear in the ensemble film Berlin, I Love You and the French crime thriller film Anna, the latter directed and written by Luc Besson.
