Background: Adele Laurie Blue Adkins was born on 5 May 1988 in Tottenham, London, to an English mother, Penny Adkins, and a Welsh father, Marc Evans. Evans left when Adele was two, leaving her mother to raise her. She began singing at age four and asserts that she became obsessed with voices. Growing up, Adele spent most of her time singing rather than reading; the last book she read was Roald Dahl's Matilda when she was six years old.
Context: Adele is a mezzo-soprano with a range spanning from C3 to B5. However Classic FM state she is often mistaken for a contralto due to the application of a tense chest mix to achieve her lower notes, whilst also noting that her voice becomes its clearest as she ascends the register, particularly from C4 to C5. Rolling Stone reported that following throat surgery her voice had become "palpably bigger and purer-toned", and that she had added a further four notes to the top of her range. Initially, critics suggested that her vocals were more developed and intriguing than her songwriting, a sentiment with which Adele agreed. She has stated: "I taught myself how to sing by listening to Ella Fitzgerald for acrobatics and scales, Etta James for passion and Roberta Flack for control."  Her voice has received acclaim from critics. In a review of 19, The Observer said, "The way she stretched the vowels, her wonderful soulful phrasing, the sheer unadulterated pleasure of her voice, stood out all the more; little doubt that she's a rare singer". BBC Music wrote, "Her melodies exude warmth, her singing is occasionally stunning and, ...she has tracks that make Lily Allen and Kate Nash sound every bit as ordinary as they are."  For their reviews of 21, The New York Times' chief music critic Jon Pareles commended Adele's emotive timbre, comparing her to Dusty Springfield, Petula Clark, and Annie Lennox: "[Adele] can seethe, sob, rasp, swoop, lilt and belt, in ways that draw more attention to the song than to the singer". Ryan Reed of Paste magazine regarded her voice as "a raspy, aged-beyond-its-years thing of full-blooded beauty", while MSN Music's Tom Townshend declared her "the finest singer of [our] generation".

Problem: Background: A burlesque is a literary, dramatic or musical work intended to cause laughter by caricaturing the manner or spirit of serious works, or by ludicrous treatment of their subjects. The word derives from the Italian burlesco, which, in turn, is derived from the Italian burla - a joke, ridicule or mockery. Burlesque overlaps in meaning with caricature, parody and travesty, and, in its theatrical sense, with extravaganza, as presented during the Victorian era. "Burlesque" has been used in English in this literary and theatrical sense since the late 17th century.
Context: Victorian burlesque, sometimes known as "travesty" or "extravaganza", was popular in London theatres between the 1830s and the 1890s. It took the form of musical theatre parody in which a well-known opera, play or ballet was adapted into a broad comic play, usually a musical play, often risque in style, mocking the theatrical and musical conventions and styles of the original work, and quoting or pastiching text or music from the original work. The comedy often stemmed from the incongruity and absurdity of the classical subjects, with realistic historical dress and settings, being juxtaposed with the modern activities portrayed by the actors. Madame Vestris produced burlesques at the Olympic Theatre beginning in 1831 with Olympic Revels by J. R. Planche. Other authors of burlesques included H. J. Byron, G. R. Sims, F. C. Burnand, W. S. Gilbert and Fred Leslie.  Victorian burlesque related to and in part derived from traditional English pantomime "with the addition of gags and 'turns'." In the early burlesques, following the example of ballad opera, the words of the songs were written to popular music; later burlesques mixed the music of opera, operetta, music hall and revue, and some of the more ambitious shows had original music composed for them. This English style of burlesque was successfully introduced to New York in the 1840s.  Some of the most frequent subjects for burlesque were the plays of Shakespeare and grand opera. The dialogue was generally written in rhyming couplets, liberally peppered with bad puns. A typical example from a burlesque of Macbeth: Macbeth and Banquo enter under an umbrella, and the witches greet them with "Hail! hail! hail!" Macbeth asks Banquo, "What mean these salutations, noble thane?" and is told, "These showers of 'Hail' anticipate your 'reign'". A staple of burlesque was the display of attractive women in travesty roles, dressed in tights to show off their legs, but the plays themselves were seldom more than modestly risque.  Burlesque became the speciality of certain London theatres, including the Gaiety and Royal Strand Theatre from the 1860s to the early 1890s. Until the 1870s, burlesques were often one-act pieces running less than an hour and using pastiches and parodies of popular songs, opera arias and other music that the audience would readily recognize. The house stars included Nellie Farren, John D'Auban, Edward Terry and Fred Leslie. From about 1880, Victorian burlesques grew longer, until they were a whole evening's entertainment rather than part of a double- or triple-bill. In the early 1890s, these burlesques went out of fashion in London, and the focus of the Gaiety and other burlesque theatres changed to the new more wholesome but less literary genre of Edwardian musical comedy.
