Artists affected by floods in Louisiana may seek help from the Joan Mitchell Foundation Emergency Program. From the New Orleans Advocate story:
One of the devastating things about this flooding is that it came on so quickly. We’re reaching out to artists in hope that they will share information about these grants through their peer network. The turnaround process can be fairly quick,” Blatchford said.
A prompt response helps get artists back on their feet, but applications are accepted on a rolling basis with no set deadline.
