Pianist Leon Fleisher will conduct and appear as soloist with the Pacific Symphony on May 23 and 24 at the Orange County Performing Arts Center, orchestra officials announced Wednesday. Fleisher replaces Sergiu Comissiona, who bowed out of the engagement in February to assume his new duties as music director for the Vancouver Symphony. Fleisher already had been scheduled to appear on those dates as soloist in Ravel’s Concerto for the Left Hand. He will conduct the work from the keyboard and will assume the podium for Rachmaninoff’s Symphony No. 2 and Beethoven’s “Coriolan” Overture. Tickets: $9 to $30. Information: (714) 740-2000.

A 10-member interim executive committee has been appointed to steer the South Coast Symphony until the end of June, succeeding a three-member board formed in January of 1989 to resolve financial problems which had led to cancellations and postponements of several concerts. The orchestra’s general manager, Doreen Hardy, says those issues have been sufficiently resolved to allow wider management through the new committee-- which will, in turn, be replaced by a new board of directors to be elected by July 1. Members of the current committee are Richard Burrell and James LeNeve, co-chairmen; Carole Stevens, secretary; Herbert Schwartz, treasurer; William Crosby; Ron Monat; Karl F. Pister; Sally Anne Sheridan; Peter Tennyson and Albert Wong. Burrell, Sheridan and Wong had been the three members of the first interim board.
