I would guess they are NOT going to play Revolution Hall the night after playing Red Square. Since the 2 venues are about 15 miles apart as the crow flies I think that is too close geographically. Additionally, Rev Hall is being operated/booked by different folks since the last time the Breakfast played there.
Unfortunately for the BKFST I am thinking this 09/14 date is Rosh Hashana weekend which is a school holiday for SUNY and most colleges in this area. As a result, the attendance possibilities are lower. I live in the area but have no ability to flyer, however, if there were flyers available before Labor day weekend I would make sure they got some coverage in the Lark street area and at the Honest Weight Co Op which is the co op where many students shop.
BTW, Red Square IS A nice bar, they do have hot bar tenders, but the capacity of the music room/dance floor is only about 300. The only band I have ever seen pack the place is RAQ.
