Yesterday, we went to the Roy Thomson Hall and attended a free organ performance featuring Frederic Champion. Frederic Champion is a famous organist. According to the programme notes, he has won many prizes at many important international organ competitions. It is a regret that I couldn't appreciate the performance because I didn't know the background and the content of the music. In fact, it is very difficult for me to understand classical music, especially about religion. Anyway I would like to thank my teacher Joseph because he introduced many buildings to us, which are all symbols of Toronto.
