Dance music star Moby had to pull out of a Dj set at an inauguration gala in Washington, D.C. on Sunday (20Jan13) and rush back to Los Angeles due to a mystery "personal issue".

The Porcelain hitmaker was expected to provide the music at The Peace Ball: Voices of Hope and Resistance to honour the work of those fighting for continued peace and justice across the world, but he had to skip the event at late notice.

Taking to his Twitter.com page to explain his no-show, he writes, "i was terribly sorry to miss the peace ball. unfortunately i had a serious personal issue that required me to rush home. i'm sorry."

No further details about the private problem were available as Wenn went to press.
