Task: Question Generation
Input (English): Passage: Bowie's songs and stagecraft brought a new dimension to popular music in the early 1970s, strongly influencing both its immediate forms and its subsequent development. Bowie was a pioneer of glam rock, according to music historians Schinder and Schwartz, who credited Marc Bolan and Bowie with creating the genre. At the same time, he inspired the innovators of the punk rock music movement. When punk musicians were "noisily reclaiming the three-minute pop song in a show of public defiance", biographer David Buckley wrote that "Bowie almost completely abandoned traditional rock instrumentation." Bowie's record company promoted his unique status in popular music with the slogan, "There's old wave, there's new wave, and there's David Bowie".Musicologist James Perone credited Bowie with having "brought sophistication to rock music", and critical reviews frequently acknowledged the intellectual depth of his work and influence. The Human League founder Martyn Ware remarked that he had lived his life "as though he were an art installation." The BBC's arts editor Will Gompertz likened Bowie to Pablo Picasso, writing that he was "an innovative, visionary, restless artist who synthesised complex avant garde concepts into beautifully coherent works that touched the hearts and minds of millions". U2 lead singer Bono commented, "I like Bowie when he’s evenly pulled in the direction of being a pop star and Picasso, where he's right down the middle. That’s usually my favorite, when the songwriting is disciplined but the recording is not. I love when he's pulled equally in the directions of art and populism."Broadcaster John Peel contrasted Bowie with his progressive rock contemporaries, arguing that Bowie was "an interesting kind of fringe figure... on the outskirts of things". Peel said he "liked the idea of him reinventing himself... the one distinguishing feature about early-70s progressive rock was that it didn't progress. Before Bowie came along, people didn't want too much change". Buckley called the era "bloated, self-important, leather-clad, self-satisfied"; then Bowie "subverted the whole notion of what it was to be a rock star".
After Bowie there has been no other pop icon of his stature, because the pop world that produces these rock gods doesn't exist any more. ... The fierce partisanship of the cult of Bowie was also unique—its influence lasted longer and has been more creative than perhaps almost any other force within pop fandom.
