1972 – Not a great day in Jefferson Airplane history. First police receive a bomb threat before their show in Akron, Ohio. The heavy pig presence incenses the crowd, who throw rocks at a police car. The cops respond by using tear gas, which causes Airplane bassist Jack Casady to denounce them from the stage. He’s arrested. Singer Grace Slick and guitarist Paul Kantner give chase after Casady is taken to the venue’s basement and, after an exchange, Slick is maced in the face and Kantner is knocked to the floor by overzealous cops.
