It's a little hard to describe n+1 because n+1 belongs in another time. If Mary McCarthy were alive today, it is the journal she would write for. Its four editors met at Harvard, live in New York City, and like ideas. All they really want to do is go around the corner and get a beer and talk/fight about Isaac Babel or Radiohead or McSweeney's or the state of American fiction or how much exercise sucks. Tonight, two of the editorial brass, Keith Gessen and Chad Harbach, read from issue number six. (Elliott Bay Book Company, 101 S Main St, 624-6600. 7:30 pm, free.)
