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.
Tempesta di Mare – Philadelphia Baroque Orchestra received support for two seasons of performances and modern-day premieres of mostly unpublished works by German Baroque composer and Bach contemporary Johann Friedrich Fasch (1688–1758). Tempesta di Mare worked from newly constructed editions by co-artistic directors Richard Stone and Gwyn Roberts. The project featured Tempesta's violinist and concertmaster Emlyn Ngai and lutenist Richard Stone as concerto soloists. The performances also formed the basis for two premiere recordings of project repertoire on the British label Chandos.
