New in paperback. Hardcover was published in 2021. Taking Adorno and Horkheimer's "The Culture Industry" and Adorno's Aesthetic Theory as key touchstones, this book explores the ever-urgent notion that high culture has become deeply enmeshed with popular culture. This is "Gaga Aesthetics": aesthetics that no longer follows clear fields of activity, where "fine art" is but one area of critical activity.
