Analyzing the development of the audience composition in classical music, two trends have been dominant since the mid-1990s: the market is steadily aging and shrinking. The concert is losing relevance as both an aesthetic and a social institution. A look into the history of concert culture shows that this trend can be countered with changed forms of presentation. This means that in order for concerts to regain their attractiveness, they must undergo transformation. Renowned authors from musicology and the music industry, as well as from sociology, economics, and cultural studies, provide insights and examples for new performance concepts in this volume, which is now being released in a completely revised second edition, aimed at contemporarily advancing the art form of the concert.
