Mainly Mozart to Expand With Concert in January : Chamber music: Added performance is aimed at keeping public awareness of the June festival alive.

Presenting its first public concert outside its annual June series, the Mainly Mozart Festival announced Monday that it will sponsor the Cleveland Quartet on Jan. 9 at the downtown Doubletree Hotel.

“Bringing the Cleveland Quartet to perform is logical for us,” festival general manager Nancy Laturno said, “since half of the quartet is from our festival roster.”

Festival concertmaster William Preucil is Cleveland’s first violinist, and festival co-principal violist James Dunham is the quartet’s violist. Both musicians have been with Mainly Mozart since its founding in 1989 by David Atherton, the British conductor who was music director of the San Diego Symphony from 1981-87 and is now music director of the Hong Kong Philharmonic.

Laturno added that the festival does not intend to compete with the La Jolla Chamber Music Society as a local presenter of chamber music.

“The programs we present outside of Mainly Mozart will all have some obvious tie to the festival,” she said. “It will also be a way to keep public awareness of the festival alive throughout the year.”

The Cleveland Quartet is in residence at the Eastman School of Music in Rochester, N. Y., and makes its summer home at Colorado’s Aspen Festival. The ensemble’s Jan. 9 program, to be given in the hotel’s ballroom, will include Mozart’s G Major Quartet, K. 387, Schubert’s A Minor Quartet, Op. 29, and Ravel’s F Major Quartet.

The Doubletree Hotel, near the Spreckels Theatre, where festival performances are held, will also function as the 1993 Mozart Festival’s host hotel.
