"Bass-baritone Sir Bryn Terfel will replace baritone Dmitri Hvorostovsky in the Boston Symphony Orchestra's , opera gala program at Tanglewood. Led by BSO Music Director Andris Nelsons, the program will feature Sir Bryn, soprano Kristine Opolais, and the Tanglewood Festival Chorus in an evening of opera and song. Further program details will be announced at a later date. Mr. Hvorostovsky withdrew from the concert in May for reasons of health."Hvorostovsky was diagnosed with a brain tumor in the summer of 2015 and subsequently cancelled concerts in Kaliningrad, Minsk and Vienna, as well as performances in the Met's production of Tchaikovsky's Eugene Onegin, where he was replaced by fellow barihunks Peter Mattei and Mariusz Kwiecien. In April, he did make an appearance in Toronto with Anna Netrebko and Yusif Eyvazov.
His website lists two concerts at the Grafenegg Festival on June 22 and 23 titled "Hvorostovsky and Friends."
