Tree.Lock//Productions mounts its second show with I Have to Pay My Rent running at Joe’s Steak + Soda Shop in Fishtown on September 12, 19, 26, and October 3. This “theatrical installation” will find creator Sterling Melcher’s audience seating themselves in the restaurant alongside other patrons during the last hour of business. They can order a cheesesteak as well as some art: snippets of Melcher and his collaborators’ unfinished stuff, like poems, songs, novels, plays, and other concepts. The performance asks why these works were never finished, and how and whether the artists should resume them: it’s “a reflection in action on what it is like to be stuck between making money and making art.”
