Gaslight District, The Second City e.t.c., open run. The 42nd revue at The Second City’s “junior” stage waxes sardonic about Trump, improvises a song, cleverly incorporates an audience member and trumpets (perhaps unnecessarily) its multiethnic, multiamorous cast. JA

Sweeney Todd, Theo Ubique Cabaret Theatre at the No Exit Café, through May 20. Sondheim’s operatic musical changed the history of the genre and this is your last chance to see it up close and cozy as only Theo Ubique’s back-street hidaway can present it.MSB

Frost/Nixon, Redtwist Theatre, through May 20. Longtime audiences will barely recognize Redtwist regular Brian Parry, serving up a portrait of American archvillain Richard Nixon so vividly charismatic as to almost—almost, I said—exonerate him for his criminal legacy. MSB

Prometheus Unbound, City Lit Theatre, through June 10. Aeschylus’ ancient tale of Prometheus’ crime and Zeus’ punishment is adapted by from the Greek by scholar Nicholas Rudall and featuring a cast of human-sized puppets alongside actual humans. CES
