Fear, organized. Brian Rea, organizer of worry, “I discovered like most people I had a lot of fears — after a few months, I began to catalog them: physical fears, natural fears, political fears, random, emotional.” After 11 years in New York, he made lists of his own and those of the people around him to fill up a 7-meter-by-3.5-meter wall, an exhibition at the Joan Miró Foundation in Barcelona called Murals.
