Here's what we know so far.

The official name of the concert is "12-12-12 (A Concert for Sandy Relief)."

It will be held at Madison Square Garden and is being organized by the same folks who produced "The Concert for New York" following the 9-11 tragedy.

The organizers say the concert will be televised.

The big question is, who will perform at "The Garden" on 12-12-12?  More details on the event and the line-up are expected to be announced in the next couple of days.
