Marc Bruni, who staged Ordinary Days Off-Broadway, will direct the concert, which celebrates the cast album release of Gwon's musical. In addition to Foster, returning Ordinary Days cast members include Lisa Brescia, Jared Gertner and Kate Wetherhead with Vadim Feichtner on piano.

The 10:30 PM concert promises highlights and cut songs from Ordinary Days, as well as material from Gwon's upcoming stage projects.

Ordinary Days is billed this way: "From the bustling streets to the quiet rooftops, Ordinary Days tells the story of four young New Yorkers whose lives are unexpectedly interconnected by circumstance. The series of funny and fortuitous events in this intimate, fast-paced musical proves that ordinary days can be simply extraordinary."

Composer-lyricist Gwon's Ordinary Days, which was seen Off-Broadway last spring, also played a sold-out run at the Finborough Theatre in London, after making its world premiere at Pennsylvania Centre Stage and appearing in the 2008 NAMT Festival of New Musicals and the 2008 ASCAP/Disney Musical Theatre Workshop. His other musicals include Bernice Bobs Her Hair (with librettist Julia Jordan), The Boy Detective Fails and Ethan Frome. Visit www.adamgwon.com.
