Surrounded by Easter lilies as sunlight streamed through a stained-glass window, the renowned Orion String Quartet performed in concert at the Seabury Center on Sunday afternoon.

The concert, sponsored by the Westport Arts Center, was introduced by Peter Van Heerden, the arts center's executive director, and Russell Platt, the curator of chamber music.

The group, a resident quartet at the Chamber Music Society of Lincoln Center, played string pieces by composers Joseph Haydn (1732-1809), Robert Schumann (1810-1856) and Franz Schubert (1797-1828).

Quartet members include Daniel Phillips, on violin; his brother, Todd, also on violin; Steven Tenenbom, violist, and Timothy Eddy, cellist. The group has been playing together for more than 25 years.

Van Heerden called the event "another extension of the arts in the community, like the Dave Brubeck tribute at the Pequot Library recently."

Platt, who has been curating the WAC chamber series for the past six years, was impressed with the group's fluidity. "I've never heard a group more in synch with each other."
