On its surface, Edward Gant’s Amazing Feats of Loneliness is about a troupe of traveling, Edwardian circus-esque performers reenacting preposterous tales of heartache out of the back of a truck. Underneath the sheen of improbability and performativity, however, lie big questions about life, humanity, storytelling, and, perhaps most importantly, the point of theater. The tales, or feats of loneliness as it were, become more elaborate and bizarre as the show wears on — a young Italian girl’s pimples transform into pearls when popped, a soldier undergoes brain surgery in a cave in Nepal in order to forget his lost love, a forgotten teddy bear’s only wish is for imaginary tea and cake, etc. — until they reach a point that’s so absurd a company member brings the play forcibly to a halt, refusing to participate in the spectacle any longer. It’s wondrous and weird and just a touch crass — plus, the final bow is a literal show-stopper.
