The Philharmonia Baroque Orchestra and Chorale has announced that Music Director Richard Egarr has withdrawn from the company’s upcoming tours due to medical reasons.

He will be replaced by John Butt and David Belkovski.

The ensemble is set to tour throughout Europe and the U.S. east coast in July and August with stops at the Ryedale Festival, St. Martin-in-the-Fields, and the Concertgebouw, as well as the Norfolk Chamber Music Festival. Butt will take over the first three stops while Belkovski will conduct at the final one in August; Belkovsky will also perform on July 28 in a candlelit harpsichord recital.

Butt is a conductor, organist, harpsichordist, and Bach scholar who has worked with such organizations as Orchestra of the Age of Enlightenment, The English Concert, The Irish Baroque Orchestra, The Royal Academy of Music Bach Cantata series, the Scottish Chamber Orchestra, the Portland Baroque Orchestra and the Stavanger Symphony Orchestra, and most prominently, the Dunedin Consort, which who he earned a Grammy award for recordings of Händel’s “Messiah” and Mozart’s “Requiem.” He also founded the Philharmonia Chorale in 1995.

Belkovski is the Philharmonia Baroque Orchestra and Chorale’s new assistant conductor.
