2 new plays

'The Afterlife of J.

Edgar Hoover, now dead of course, and his young "caretaker," also dead. Directed by Dick Reichman and presented by Cyrano's Theatre Company and RKP Productions. 7 p.m. Thursdays-Saturdays and 3 p.m. Sundays through April 23, 411 D St. $23-$25.

'Picasso at the Lapin Agile': This fast-paced absurdist comedy, written by the legendary comedian Steve Martin, places Albert Einstein and Pablo Picasso in a Parisian cafe in 1904, just before Einstein transformed physics with his theory of relativity and Picasso set the art world on fire with cubism. The two muse on the century's achievements and prospects, before being visited by a third genius from the future. 8 p.m. Friday-Saturday and 5 p.m. Sunday, UAA Harper Studio, 3700 Alumni Loop. $10-$20.

Arctic Entries

April's Arctic Entries is this week. In case you haven't been, this is the event wherein seven people each tell a seven-minute-long true story relating to the show's theme, and local musicians perform a few songs as well. This show's theme is "It Takes Two: Stories Told in Tandem." 7:30 p.m. Tuesday, Alaska Center for the Performing Arts. Tickets are $15 at centertix.net.

*Editor's note: A previous version of this story stated that the last Arctic Entries show of the season is this week. In fact, there is one more before summer, on Tuesday, May 9. The story also incorrectly listed the length of the pond for the Slush Cup as 90 inches instead of 90 feet.
