It looks like a hedge fund holiday season this year at New York's Lincoln Center. One of the season's big musical performances is underwritten in part by donations from Bruce Kovner. Thanks to the Caxton Associates founder, the a cappella sextet known as the King's Singers will be performing works on December 8 that range from the Medieval period to the present. But Kovner isn't the only hedge fund Claus this season. In early January, the New Year's gala at Lincoln Center will be backed by industry legend and Duquesne Capital Management founder Stanley Druckenmiller.
