(previews start on Tuesday; opens on May 3) Sibyl Kempson, a playwright of indelible and unforced weirdness, launches a new theater company, the 7 Daughters of Eve Thtr. & Perf. Co. For its inaugural production, Ms. Kempson has created, according to the Abrons Arts Center's website, "an irrational musical contemplation of the ethical pitfalls of poetic journalism," inspired by James Agee, Susan Sontag and contemporary performance art.
