The tenor noted, “My dear friends and family, dear fans in the Chicago area, I’m sorry to let you know that I have to withdraw from the ‘CSO: Italian Opera Favorites’ concert at the Ravinia Festival on August 11. This has been a tough year for me healthwise, but I am confident I will be back this fall at Lyric Opera of Chicago for Idomeneo. Until then I offer you all my sincerest apologies and my grateful thanks to the Ravinia Festival who have been completely supportive and fabulous during this time. I wish you all a wonderful and restful summer.”
