There is always music inspired by, and that  inspires,  political resistance, and these times are no exception.  Radical musicologist Brad Duncan talks with Bill Resnick about some recent currents in political music, some of which were heard on today's Old Mole:  "Tina," by the Mekons, "El Pueblo Unido," by Thievery Corporation, "Which Side Are You On," by Rebel  Diaz, and "Celtic Tiger," by Damien Dempsey.
