Gwyn Roberts and Richard Stone, baroque performers and educators of international renown, believe in ensemble. They are co-founders of the highly successful (and widely traveled) Tempesta di Mare, the Philadelphia Baroque Orchestra, which opens its 15th anniversary season with concerts Oct. 21-23. Talking to them on a joint phone call about their vision was like engaging with two deeply intertwined chamber players: complementary phrases were tossed back and forth seamlessly.
