John Steinbeck's classic novel "The Grapes of Wrath" will be celebrating its 75th anniversary next year.

The 1939 novel tells the story of the Joad family, who make the long trek from Oklahoma to California along Route 66 during the Great Depression.

To commemorate the upcoming anniversary, three artists are retracing the Joad family's trip and talking to people along the way.

Playwright  Octavio Solis, joined by filmmaker PJ Palmer and visual artist Patricia Wakida, traveled along  Route 66 and collected audio stories of what motivates people to keep going forward in difficult times.
