The immediate physical presence of color is central to Katharina Grosse's creative endeavor. Through an open-ended creative process in which painting takes on the form of a performance, color embodies movement, making its emotional potential tangible. These issues are not only driving her dramatically large in situ works painted across various surfaces in public places. They also inform her studio paintings, which have played an equally central role in her practice from the start. This book is the first study focusing on Grosse's studio practice from the late 1980s to the present. Five essays and an insightful interview with the artist explore how Grosse expands the concept of painting - not just in open space, but also on canvas - through creating an ephemeral character and removing the limitations of its traditional frame.
