Hanne Darboven (1941-2009) is one of the twentieth century's most extraordinary international artists. This major publication brings together key works from all phases of her prolific career spanning over fifty years. It highlights the outstanding and wide-ranging output of this key conceptual artist in its entire temporal and stylistic breadth, featuring works in which the artist focuses on political events, German history and her personal context and shows the extensive work series exploring themes from cultural history, music, literature, and (natural) science. Beside the serial calculations on paper the book also presents parts of the artist's studio in Hamburg: The desks, for example, tell us of Darboven's systematic approach to her work. The so-called music room, a quasi-encyclopedic archive, grants insight for the first time into the intellectual cosmos of the artist and her practice of compilation, composition and notation.
