Under artistic director Yorgos Loukos, the Athens and Epidaurus Festival “has been transformed from a moribund event into a vibrant arts experience. … Mr. Loukos, a genial round-faced man, has made sweeping changes that have radically altered the nature of the festival. First he reduced the leisurely five-month Athens portion to two high-concentration months in June and July. Then he set about finding new sites to expand performance possibilities and audiences.”
