What is hiding in the material choices of artists and makers? Immaterial, The Metropolitan Museum of Art’s marquee podcast, is back with eight more episodes that reveal the emotional origins and transformative power of art through the lens of materials. This season we learn from Mexican artisans keeping centuries-old traditions alive; we go to ancient Mesopotamia to understand time travel; and we find a mythical tree in Belize that’s been making music for decades. From traditional materials like stone and wood, to more abstract ones like space and time, the podcast explores how these materials shape the inner lives of artworks and the human experiences they reflect. Season 2 of Immaterial drops June 4.
