Kate Whoriskey directs a reading cast that includes Roger Rees and Frank Wood.

In the play, a quartet celebrating its 10th anniversary is on the brink of a major New York City concert, allowing for tensions to be exposed.

The readings in the "6@6" series are coordinated by MTC's play development department. Five plays and one musical are in the spring series this year.

David Auburn's Proof was heard in "6@6" before MTC shepherded it to a full Off-Broadway staging and then (with producing partners) to Broadway. It won the Pulitzer Prize for Drama and the Tony Award for Best Play.

Works heard in the series are generally making their New York reading debuts. Each reading takes place on a Monday night at 6 PM on the 8th floor of Manhattan Theatre Club's Creative Center, 311 West 43rd Street between Eighth and Ninth Avenues. For information, call (212) 399-3000 ext. 163. Reservations are recommended as seating is limited.
