Tempesta di Mare – Philadelphia Baroque Orchestra performs baroque music on baroque instruments with a repertoire that ranges from staged opera to chamber music. The group performs all orchestral repertoire without a conductor, as was the practice when this music was new. Led by directors Gwyn Roberts and Richard Stone with concertmaster Emlyn Ngai, the ensemble is the only American baroque music group to record for the prestigious British label Chandos. Over the course of its 2013–14 and 2014–15 seasons, the ensemble presented Tragédie et Comédie, a Center-funded concert series of French baroque orchestral music played on period-specific instruments. In 2016, Tempesta received a Center grant to present Telemann 360º, a two-part concert program combined with a live talk show hosted by Live from Lincoln Center's Fred Child, and an accompanying studio recording that will offer a fresh perspective on the artistic legacy of baroque composer Georg Philipp Telemann.
On the heels of a highly successful five-year plan that refined the organization's artistic mission and developed strategies for performance and internal growth, Tempesta di Mare – Philadelphia Baroque Orchestra launched a new three-year plan with the assistance of David Bury of David Bury and Associates, who works extensively with growing arts organizations and whose experience extends to touring music organizations. This new plan met Tempesta di Mare's enhanced needs as an established, internationally recognized orchestra, and has addressed new artistic opportunities, such as a recording contract with British record label Chandos and a performance at a major international festival in Germany. As a result, Tempesta di Mare has dramatically increased its profile internationally, and has significantly expanded its audience through social media and its own YouTube channel.
