traffic, barking dogs, and advertisements follow the character of Theo through London, East Sussex and Kent, producing what Los Angeles Times writer Kevin Crust called an "urban audio rumble". Crust considered that the music comments indirectly on the barren world of Children of Men: Deep Purple's version of "Hush" playing from Jasper's car radio becomes a "sly lullaby for a world without babies" while King Crimson's "The Court of the Crimson King" make a similar allusion with their lyrics, "three lullabies in an ancient tongue". Amongst a genre-spanning selection of electronic music, a remix of Aphex Twin's "Omgyjya Switch 7", which includes the 'Male Thijs Loud Scream' audio sample by Thanvannispen can be heard during the scene in Jasper's house, where Jasper's "Strawberry Cough" – a potent strain of cannabis known for its mysterious origins, its aroma of strawberries, and its mood lifting properties – is being sampled. During a conversation between the two men, Radiohead's "Life in a Glasshouse" plays in the background. A number of dubstep tracks, including "Anti-War Dub" by Digital Mystikz, as well as tracks by Kode9 & The Space Ape, Pinch and Pressure are also featured. For the Bexhill scenes during the film's second half, Cuarón makes use of silence and cacophonous sound effects such as the firing of automatic weapons and loudspeakers directing the movement of refugee. Classical music by George Frideric Handel, Gustav Mahler, and Krzysztof Penderecki's "Threnody to the Victims of Hiroshima" complements the chaos of the refugee camp. Throughout the film, John Tavener's Fragments of a Prayer is used as a spiritual motif.
