Fine-tuned affair

Forget stuffy. From a square-dance exhibition during the champagne reception in the Tiffany Room to a fiddler leading the way to the formal dinner in the Crystal Ballroom, the Los Angeles Chamber Orchestra’s “Bach to Bluegrass” gala at the Biltmore Millennium Hotel Jan. 24 was both classic and country. Guest artists Edgar Meyer on double bass and Bela Fleck on banjo performed works such as Bach’s “Three Inventions” and Fleck’s “County Clare” at the annual benefit for the chamber orchestra, founded in 1968 by a group of classical music buffs who thought “L.A. was grown-up enough” for one, said Executive Director Ruth Eliel.
