Thirteen artworks that were created in response to 9/11 will go on display in New York City for the 15th anniversary of the terrorist attacks.
Paintings, sculptures, video and other media will form an exhibition at the 9/11 Memorial Museum titled "Rendering the Unthinkable: Artists Respond to 9/11." It will open September 12 and run until January.
The works, created between 2001 and 2011, will appear together for the first time.
Some of the artists lost loved ones. Others witnessed the attacks firsthand.
Two paintings by Michael Mulhern incorporate ash from the World Trade Center.
A video by the performance collective "Blue Man Group" is based on pieces of paper that landed behind its Brooklyn rehearsal space. A lot of paper was hurled out of the collapsing Manhattan towers.
