Pearl St. upstairs is about = to Premier Music Hall, or something like that... ie., bigger and nicer than most of the places Breakfast plays, but not totally out of reach at the moment or in the near future.
Going back to Pearl St. downstairs would def been seen as a step backwards by almost anybody in the Northampton area. See, Calvin, Iron Horse, and Pearl St. are all owned by the same dude, and Pearl St. downstairs is always where he sticks his acts with the least draw on a particular night. Pearl St. upstairs, on the other hand, is at least as popular as Iron Horse, but better suited to bands that don\'t put you to sleep.
