The meeting was never announced publicly. In fact, it was discovered only by accident, when a reporter from Bloomberg filed a request under the Freedom of Information Act and came across a mention of it in Bernanke's schedule. Rolling Stone has since contacted every major attendee, and all declined to comment on what was discussed at the meeting.

As a side note, somewhere I did read about discussions of that meeting. It is published somewhere but for the life of me I can't remember where I read it. I may look around in my spare time and post if I can remember where I put my memory pills.
