Combining the renegade classical sounds of San Francisco’s Kronos Quartet with the fiercely independent point of view of Alternative Radio host David Barsamian, this distinctive pairing promises global insights.

Special guest Diane Wilson, a dedicated environmental activist and author of An Unreasonable Woman: A True Story of Shrimpers, Politicos, Polluters, and the Fight for Seadrift, Texas, joins Barsamian for a discussion intertwined with fittingly progressive music.
