Louis Tyrrell directs the intermissionless drama at the resident Equity company on Manalapan, FL, near West Palm Beach. Performances continue to Nov. 26. This marks the launch of the troupe's 20th anniversary season.

"With only a few days to rehearse Beethoven's Opus 131, a world-renowned string quartet prepares for its highest-profile performance ever," according to production notes. "The rehearsal room becomes a pressure cooker as passions rise and personalities clash in this clever new work by the author of Red Herring."

The cast features Joe Kimble, Jim Shankman, Natasha Sherritt, Jeff Talbott and Craig Wroe.

The creative team includes scenic designer Kent Goetz, lighting designer Richard Crowell, costume designer Suzette Paré, production stage manager James Danford.

Opus had its world premiere at Philadelphia's Arden Theatre Company. It is nominated for several 2006 Barrymore Awards. The Barrymore ceremony is Oct. 23. For more information, visit www.floridastage.org.
