Patrick Baz, Kristine Khouri, and Emilie Madi join guest host Lyne Sneige to discuss the impact of the August 4 Beirut Port explosion on Lebanon’s artistic community; how museums and galleries are working to preserve cultural heritage; and how photojournalists recorded this tragic moment in Lebanon’s history. They are among the contributors and co-sponsors of “Lebanon Then and Now: Photography from 2006 to 2020,” an interactive virtual exhibit hosted by the MEI Art Gallery through September 30.
