Brian Culbertson will be sending an unusual item to auction soon -- and you can drink it. Posting on his Facebook page, Culbertson writes that he was given a giant bottle of Cabernet by a local vineyard. So he's been having artists who come by his studio sign the bottle -- once its filled, he'll auction it off with the proceeds going to the Grammy Foundation for Music Education. Among the names inscribed on the wine bottle so far? Dave Koz, Earl Klugh, Jonathan Butler, Jeff Lorber, Paul Jackson Jr., Phillippe Saisse, Eric Darius, Eric Marienthal and Rick Braun -- and the list keeps growing. Culbertson says he'll announce auction details soon. He's currently on the charts with one of those signatories: Earl Klugh joins him on "That's Life" from his album, XII.
