Writers-A-Go-Go! lands outdoors at Riverside Park, staged as a live event in the city’s open air. Hudson Classical Theater Company anchors the performance, folding rock and pop textures into a framework that nods to the working life of writing and the business that surrounds it. The piece treats authorship less as a solitary act than as a public transaction, shaped by money, deadlines, and audience appetite. Its plainspoken structure lets the theme register without being oversold.
