Just when La Cieca thought there could be no more opera this late in the summer, suddenly she finds out that something called REPO! The Genetic Opera opens tonight for a limited run at the Wings Theater on Christopher Street. The piece is described so: “a futuristic rock musical, Repo! takes place during an epidemic of organ failure and captures the resulting frenetic harvesting of human organs, collected by brutal genetic repo men.” The website also promises “folding giant penis greeting cards,” and it goes without saying you can never have too many of those.
