The Tokyo String Quartet will open the Laguna Beach Chamber Music Society's expanded 30th season on Oct. 7 at Laguna Beach High School, society officials announced Wednesday.
The society has incorporated a Young Artists concert into the 1989-90 main series, raising the season's concert total to seven.

-- Oct. 7: Tokyo String Quartet.
