We're talking about a prison-industrial complex. We're talking about a war on drugs that's generating unprecedented levels of incarcerated folk. We're talking about dilapidated housing. We're talking about joblessness and underemployment.

I think Martin Luther King would always keep track of collective insurgencies among poor and working people. He was concerned about the treatment of Jews in the Soviet Union, for example. He would have closely followed the Arab Spring. And certainly he would be very critical of the massive surveillance state that has emerged in America in the last five to 10 years. He would have approved of the movements trying to gain some accountability in U.S. foreign policy, such as drones being (used) on innocent people. I think he would march against drones.

I'm a bluesman moving through a blues-soaked America, a blues-soaked world, a planet where catastrophe and celebration... "Joy and Pain" - sit side by side. The blues started off in some field, in some plantation, in some mind, in some imagination, in some heart. The blues blew over to the next plantation, and then the next state. The blues went south to north, got electrified and even sanctified. The blues got mixed up with jazz and gospel and rock and roll.
