Nick Cave’s palate is wickedly broad in scope. The veteran Australian singer, songwriter and bandleader is a complex storyteller, a master of the dark arts who's equally adept at touching one’s soul with the tenderness of an "Into My Arms" or a "Ship Song".Political songs, however, just aren’t part of his DNA.In a new entry to his Red Hand Files blog, Cave offered a thoughtful response to a query on whether he wishes he’d tackled “political” themes in his songs.He would if he could.
