Michael Bush, the new artistic director at the Emelin Theatre, is staking out his territory in Mamaroneck with a new mainstage season and a 20-day festival that features plenty of Tennessee - Williams and otherwise. Bush, who comes to the Emelin from Manhattan Theatre Club, is giving his new audience a sense of his strengths, and the things he has a weakness for, with the “Theatre in Concert Festival,” kicking off Nov. 17.

These are the shows Bush has been working on recently, brought together as sort of a recent rйsumй, even though he’s already got the job. The festival begins with Tennessee Williams at the end of his life, in a show titled “Everyone Expects Me to Write Another Streetcar.” Culled from the playwright’s memoirs and from interviews, the drama stars Jeremy Lawrence and runs Nov. 17 and 18. Near the end of the festival, on Dec.

1 and 2, the Emelin will present “Becoming Tennessee,” a musical by Clint Edwards and Michael Aman that covers Williams’ first visit to New Orleans. “Williams arrived in New Orleans on New Year’s Eve 1938,” Bush says. “He arrived as Tom Williams. And when he left in March, he had changed his name to Tennessee. This musical is about those three months.” The music in “Becoming Tennessee” reminds Bush of Samuel Barber and Gershwin - “very American.” “To some ears, it’s going to seem arty.

To my ears, it’s the real thing.” Why Williams? “I’m partial to Tennessee Williams,” Bush says. “I actually look like him.” Also, Williams was a Southerner. Bush, a native of Charlotte, N.C., grew up on him. Bush makes a Tennessee connection of another kind on Dec. 1 and 2, with “A Tribute to the Bluebird Cafe: The Sounds of Nashville,” starring Marcus Hummon and Sherrie Austin. The artistic director just finished directing Hummon’s musical “The Piper” for the New York Musical Theater Festival.
