Klaus Richter opens his monologue: “I am Klaus. I am a sad German man who goes on trips.” Part travelogue, part cry for help, Klaus relates his trips to Williamsburg, to Disneyland, and on ayahuasca. The one-act monologue, written and performed by comedian Nick Zielinski, is entitled “Be Not Afraid, Klaus,” and was performed last Friday at a (literally) underground theater at the Tea Factory Lofts. Walk through someone’s kitchen, down a rickety wooden staircase in total darkness and you will be at NXT LVL, a theater space with shiny black walls, exposed light bulbs, and wide wooden benches. Here, in an accented monotone and with a perpetual thousand-mile stare, his only prop a white porcelain horse head, Klaus tell us his impressions of America in general and our little part of America in particular.
