On the Myfountainsquare.com website, a very promising summer line up of programming is scheduled, including an interesting one called "Rock the Square" which seems to be set for most every Friday. Many of those events are tied to larger local festivals/events taking place on that Friday. One of the first one's is slated to be themed for the Cincinnati Fringe Festival.
What is missing is a line-up of acts. It is very hard to book that far ahead, but when it comes to music you have to consider you music fan likes to know who they are going to see well ahead of the day of the event. If anyone has an idea of any acts playing "Rock the Square," please let me know. I got a quick response from the folks at CinWeekly, so we might get someone with first hand knowledge to chime in.
