That was quick.

Elizabeth Herridge, the former managing director for the Guggenheim Hermitage Museum, was appointed June 11 as interim executive director for the Las Vegas Philharmonic.

This week she was clearing out her office.

No word yet on the reason for her departure, but the Philharmonic had anticipated Herridge's employment to last through the summer.

In a June 11 press release, Herridge is quoted as saying, "I am thrilled to take on a leadership role at The Las Vegas Philharmonic

and to increase my participation and support of the orchestra. Las Vegas is a city of enormous opportunity and cultural vitality. I look forward to furthering the interests and development of the Philharmonic as an integral part of the Las Vegas community and the larger arts community."

The changes won't affect the Las Vegas Philharmonic's concert at Hills Park in Summerlin on Friday. The annual Fourth of July concert features Brent Barrett, Broadway tenor and former star of "Phantom, the Las Vegas Spectacular." The orchestra will be conducted by music director David Itkin and associate conductor Richard McGee. The program includes a George M. Cohan medley, Tchaikovsky’s “1812 Overture” and fireworks. Tickets are $30 at the gate, $25 for children 6-12, children 5 and under are free.
