Two of Mac Wellman's better known plays, Sincerity Forever and Cleveland, will be presented by the Bat Theatre Company at Tribeca's Flea Theatre this spring. Sincerity Forever began performances on April 26 and will run through May 26. Cleveland will join the bill on May 10, also running through May 26. Laramie Dennis directs.

The 1991 Sincerity Forever won an OBIE Award. The plot concerns Judy and Molly, members of the "Invisible Nation" in Hillbottom, U.S.A.; Hank and Tom, two junior-college drop-outs; the Mystic Furballs, a pair of powerful and powerfully ugly creatures; and "a supremely wise woman with a very heavy suitcase."

1986's Cleveland actually takes place in a town you've heard of, the urban center of the title. There, a mother and daughter enact a very Wellmanesque take on kitchen sink realism.

Dennis first directed Cleveland at the Flea in 1999. Since then she has helmed The Learned Ladies at New Jersey Shakespeare Festival, Freedomland at the Atlantic Theatre Studio, and various works as Soho Rep, the adobe theatre company and Theatre for the New City. She co chairs Soho Rep's playwrights-directors lab and is a resident director at the Flea.

Tickets are $15. Cleveland runs at 7 PM; Sincerity Forever at 10 PM. For more information, call (212) 226-2407. —By Robert Simonson
