It's possibly one of the most denigrated inventions in the history of music; the greatest signifier of rock star pomposity. Indeed, in some quarters, the very mention of it is likely to provoke sniggering derision, conjuring up images of quadruple-gatefold album sleeves, songs that go on for weeks and straggly-haired rockers prattling on about mystical lands, unicorns, goblins ...$现在好多pop star强行要把自己的专辑拼盘成concept album真的很无语,真正有主题的concept album都是很伟大集艺术人格一体的。
