Played the Sibelius Third tonight. In the latter part of the last movement, when he gets such a terrific bedlam going, (when you feel that gigantic forces of nature are engaged in a death struggle) you wonder how can he (Sibelius) possibly bring it all to a reasonable conclusion - end it with honor as it were - But he does with their powerful notes, like the blows of a huge hammer - a God pounding for silence.
