A song from composer-lyricist Stephen Schwartz's Wicked, the new musical that offers a revisionist history of the Wicked Witch from the "Oz" books, is being heard in the current Manhattan cabaret show, It's an Art: The Music of Stephen Schwartz.

The new producing group, The Storefront, is presenting the show, part of the troupe's series of cabaret shows devoted to specific songwriters, at The Duplex in Greenwich Village. Performances began March 11 and continue 5 PM March 18, 25 and April 1.

Schwartz wrote songs for Working, The Magic Show, Godspell, Children of Eden. The Baker's Wife, Pippin and lyrics for "The Hunchback of Notre Dame," "Pocahontas" and Rags. His new project, Wicked, is based on Gregory MacGuire's novel, "Wicked: The Life and Times of the Wicked Witch of the West."

The new song is called "Defying Gravity," and Julia Murney sings it in the evening; yes, it's a song for the witch.

The Storefront was founded in 2000 with the intent to produce plays, musicals, solo shows and cabarets. Its first venture was Taking the Wheel: The Music of John Bucchino.
