A member of a radical editorial collective on the cutting edge of British music criticism in the 1970s, later a critic for more standard papers, including the Times, David Toop'S second book covers a vast expanse of music. His tour-de-force survey describes a dissonant and invigorating clash of music and noise from western classical to Javanese gamelan, from Claude Debussy to Miles Davis to Brian Eno, from disco to techno to ambient. He discusses the changes in our sound world caused by the global reach of radio and recordings, and shows himself a rigorous pluralist, open to all styles and forms, but unafraid to offer robust criticism in any musical sphere.
