Dan Flavin is one of the most significant and influential artists of his generation. His radical use of fluorescent light throughout and beyond the 1960s forever changed the definitions and boundaries of sculptural practice.

It Is What It Is assembles for the first time key essays on Flavin and reviews of his exhibitions. Spanning four decades, it charts the gradual evolution of a consensus about the meaning of his art in texts by some of the most influential art historians and critics of today, as well as a number of essays published here for the first time in English.
