CHANGES AT BOWL GERSHWIN CONCERTS

Replacing the indisposed Lawrence Foster, conductors Neal Stulberg and Marty Paitch will lead the Gershwin program at Hollywood Bowl at 8:30 tonight and Saturday.

Stulberg will conduct “An American in Paris” and, with Christopher O’Riley as soloist, “Rhapsody in Blue.” Paitch, who serves as musical director for singer Sarah Vaughan, will lead Vaughan’s portions of the Gershwin agenda.
