Tony nominees Gregg Edelman (A Tale of Two Cities, City of Angels) and Alison Fraser (Gypsy, The Secret Garden) will be joined by Kate Shindle (Legally Blonde), John Treacy Egan (The Little Mermaid, The Producers), Laura Osnes (Grease), John Bolton (Curtains), Peter Buchi, Maya Goldman (How the Grinch Stole Christmas!) and creator Lessner for the concert. Show time is 7:30 PM.

Based on the 1993 best-selling novella by Alan Lightman, Einstein's Dreams has a book by Joanne Sydney Lessner (Fermat's Last Tango), music by Joshua Rosenblum (Bush Is Bad) and lyrics by Lessner and Rosenblum. David Loud will lead a six-piece chamber orchestra.

Einstein's Dreams, according to press notes, "finds a young Albert Einstein trapped in an unhappy marriage and an unhappy job well-beneath his intellect. The musical, like the book, places Einstein in a dreamscape that conjures up an array of theoretical realms of time, all of them visions that probe the essence of time, the adventure of creativity, the glory of possibility — and the siren call of a beautiful, elusive woman named Josette."

Songs in the musical include "Are You There?," "The End of Time," "Time Stops," "The Red Hat," "I Want to Love You," "I Will Never Let You Go," "High Speed Motion," "Now Backwards Moving Time" and "Einstein's Dreams."

The concert presentation benefits the Harpswell Foundation, an organization created in 1999 to provide education, housing and leadership training to children and young women in the developing world. (The upcoming presentation should not to be confused with Albert Innaurato and Charles Gilbert's musical adaptation of the same property. The Lessner-Rosenblum Einstein received its world premiere in 2005 at Lisbon's Teatro da Trindade.)

Tickets, ranging $21-$101, are available by phoning (212) 864-5400 or by visiting SymphonySpace.
