The CSO recording of Verdi's Requiem was honored as Best Classical Album and Best Choral Performance at the awards show.
The CSO's 2011-12 season will be announced Monday evening. It is not clear if Maestro Muti will be conducting from the start of the season. Other conductors have filled in for him since he fainted and fell from the podium during a rehearsal on February 3, 2011.
The 69-year-old underwent surgery to fix his broken jaw on February 4 and tests revealed he has a heart problem. Doctors gave him a pacemaker on February 11, 2011.
As of Friday, Muti remained at Northwestern Memorial Hospital. In a statement he said, "A music director's relationship with his orchestra is like a marriage. Together, we are a family and we bond in times of joy and in times of challenge. I think it was destiny that I came to Chicago and I think what has happened is also destiny, because now I understand and feel more comfortable than ever about returning to my work."
Officials have not said how long he will be in recovery.
