In this short book, the leading German cultural critic Diedrich Diederichsen puts forward a fresh and original account of pop music. He argues that pop music is not so much a form of music as a constellation of different media channels, social spaces and behavioural systems, of which music is only a part. Its own logic of attraction is based less on compositions and the expression of subjectivity and more on indexicality, real or pseudo-involuntary effects as recorded by sound technologies, and on studio discipline and staging, and hence on performance. By elaborating his innovative account of pop music as a constellation, Diederichsen develops a theory that distinguishes itself from sociology, cultural studies, media studies and ethnography, while at the same time drawing on and encompassing them all.
