Def Leppard are an English rock band formed in 1977 in Sheffield as part of the new wave of British heavy metal movement. Since 1992, the band has consisted of Joe Elliott (lead vocals), Rick Savage (bass, backing vocals), Rick Allen (drums, backing vocals), Phil Collen (lead and rhythm guitar, backing vocals), and Vivian Campbell (rhythm and lead guitar, backing vocals). This is the band's longest lasting line-up. The band's strongest commercial success came between the early 1980s and the early 1990s.
Rick Savage, Tony Kenning, and Pete Willis, all students at Tapton School in Sheffield, South Yorkshire, formed a band called Atomic Mass in 1977. The band originally consisted of Willis on guitar, Savage on bass (after originally playing guitar), and Kenning on drums. Only 18 at the time, Joe Elliott tried out for the band as a guitarist following a chance meeting with Willis after missing a bus, in November 1977. During his audition it was decided that he was better suited to be the lead singer. Their first ever gig was in the dining hall in A Block in Westfield School in Mosborough, Sheffield. The band adopted a name proposed by Elliott, "Deaf Leopard", which was originally a band name he thought up while writing reviews for imaginary rock bands in his English class (and in at least partial reference to Led Zeppelin). At Kenning's suggestion, the spelling was slightly modified in order to make the name seem less like that of a punk band. In January 1978, Steve Clark joined the band. According to Elliott, he successfully auditioned for the band by playing Lynyrd Skynyrd's "Free Bird" in its entirety. In November, just prior to recording sessions for what would be a three-song release known as The Def Leppard E.P., Kenning abruptly left the band; he would later form the band Cairo. He was replaced for those sessions by Frank Noon. By the end of the month, Rick Allen, then only 15 years old, had joined the band as its full-time drummer. Sales of the EP soared after the track "Getcha Rocks Off" was given extensive airtime by renowned BBC Radio 1 DJ John Peel, considered at the time to be a champion of punk rock and new wave music. Throughout 1979, the band developed a loyal following among British hard rock and heavy metal fans and were considered among the leaders of the new wave of British heavy metal movement. Their growing popularity led to a record deal with the major label Phonogram/Vertigo (Mercury Records in the US). Def Leppard's original management, MSB, a local duo consisting of Pete Martin and Frank Stuart-Brown, were fired after Martin and Joe Elliott got into a fistfight over an incident on the road. The band approached Peter Mensch of Leber-Krebs management, who had booked them on a tour of the UK supporting AC/DC. Mensch, who admitted that he had had his eye on the band, became their manager.

Answer the question at the end by quoting:

Anton Friedrich Wilhelm (von) Webern (German: ['anton 've:ban] ( listen); 3 December 1883 - 15 September 1945) was an Austrian composer and conductor. Along with his mentor Arnold Schoenberg and his colleague Alban Berg, Webern was in the core of those in the circle of the Second Viennese School, including Ernst Krenek and Theodor W. Adorno. As an exponent of atonality and twelve-tone technique, Webern exerted influence on contemporaries Luigi Dallapiccola, Krenek, and even Schoenberg himself.
Webern published little of his early work in particular; like Brahms, though perhaps for not entirely the same reasons, Webern was characteristically meticulous and revised extensively. Many juvenilia remained unknown until the work and findings of the Moldenhauers in the 1960s, effectively obscuring and undermining formative facets of Webern's musical identity, highly significant even more so in the case of an innovator whose music was crucially marked by rapid stylistic shifts. Thus when Boulez first oversaw a project to record "all" of Webern's music, not including the juvenilia, the results fit on three rather than six CDs. Webern's earliest works consist primarily of lieder, the genre that most belies his roots in Romanticism, specifically German Romanticism; one in which the music yields brief but explicit, potent, and spoken meaning manifested only latently or programmatically in purely instrumental genres; one marked by significant intimacy and lyricism; and one which often associates nature, especially landscapes, with themes of homesickness, solace, wistful yearning, distance, utopia, and belonging. Robert Schumann's "Mondnacht" is an iconic example; Eichendorff, whose lyric poetry inspired it, is not far removed from the poets (e.g., Richard Dehmel, Gustav Falke, Theodor Storm) whose work inspired Webern and his contemporaries Alban Berg, Max Reger, Arnold Schoenberg, Richard Strauss, Hugo Wolf, and Alexander Zemlinsky. Wolf's Morike-Lieder were especially influential on Webern's efforts from this period. But well beyond these lieder alone, all of Webern's music may be said to possess such concerns and qualities, as is evident from his sketches, albeit in an increasingly symbolic, abstract, spare, introverted, and idealized manner. Other works include the orchestral tone poem Im Sommerwind (1904) and the Langsamer Satz (1905) for string quartet. Webern's first piece after completing his studies with Schoenberg was the Passacaglia for orchestra (1908). Harmonically, it is a step forward into a more advanced language, and the orchestration is somewhat more distinctive than his earlier orchestral work. However, it bears little relation to the fully mature works he is best known for today. One element that is typical is the form itself: the passacaglia is a form which dates back to the 17th century, and a distinguishing feature of Webern's later work was to be the use of traditional compositional techniques (especially canons) and forms (the Symphony, the Concerto, the String Trio, and String Quartet, and the piano and orchestral Variations) in a modern harmonic and melodic language.
