I don't often get late-breaking arts news, so here you go: Just added to Town Hall's schedule, Gore will be here to discuss his new book The Assault on Reason, "an indictment of current policy making, especially the President's use of power and his handling of the war. . . the use of fear and the misuse of faith, the distractions of our entertainment culture, and the concentration of power in the national media and the executive branch." Monday at 7:30 p.m. Tickets, $5, go on sale tomorrow (Thurs.) at 10 a.m. via www.brownpapertickets.com.
