The string trio is an imaginative alternative to its cousin the string quartet. No string lover will want to miss the formidable Amerigo Trio when it performs at the Phillips Collection as part of the museum’s 90th anniversary as America’s first museum of modern art. The ensemble is a remarkable collaboration of prize-winning artists: New York Philharmonic concertmaster Glenn Dicterow, his wife, violist Karen Dreyfus, and cellist Inbal Segev. All play on priceless antique instruments with rich, warm tones.

Although they are neighbors in New York City, they did not play together until 2007 when Segev replaced an injured cellist at the International Chamber Music Festival in Bowdoin, Maine. Since forming the trio two years later, they have performed at prestigious concert series and festivals, among them Lorin Maazel’s Castleton Festival in Virginia and the New York Chamber Music Festival.
