It was broadcast @11:00-11:35 on May 3, although program page shows different schedule.
During the program, Blechacz played Chopin's Mazurka op50-2, 50-3, Polonaise op26-1, and 2, Waltz op.34-2, Bach's Italian concerto 2nd movement and Beethoven's sonata op2-2 3rd movement.
I am not for sure if this program will be broadcast as is announced on following schedule but I believe it will be sometime during the next few days.
I now found that the program is being broadcast again. (as of 13:25, May 3)
On May 6, TV Toruń will broadcast a program of Festival of Science and Arts in Toruń including the discussion of music interpretation participated by Rafał Blechacz.
May 6 @ 11:25 (??) (local time)
The program page says it is at 12:30, but I suppose it is between 11:25 and 12:00.
