Thank you for sharing this piece of sad news. I had not heard about the death myself as yet. I just wonder how this will affect Karita's performance in Prague next year in April.
The concert in Prague http://www.pkf.cz/en/191-a8-karita-mattila-paul-mccreesh/ will most probably be also a commemorative concert for Jiri Belohlavek, at least according to Karita's thoughts.
