The March For Our Lives rallies that unfolded across the country this past weekend underscored the heightened state of fear and anger over gun violence in the U.S. We open this week's show with a powerful new song from the blues and soul artist Fantastic Negrito, that he says channels his own anxieties and outrage over the state of the world, called "Plastic Hamburgers." The surprisingly loud and gritty rock cut is from his upcoming album, Please Don't Be Dead.

Also on the program: Thirty-five years into the band's career, Guided By Voices has just released a bold, infectious and ever-vital new album called Space Gun. We've got the title cut. The legendary and much beloved folk artist John Prine is back with a poignant new song called "Summer's End." And we float in the gloriously ethereal voice of Grouper, aka Liz Harris, on her new song "Parking Lot."
