I’m the first to admit that I’m playing catch-up when it comes to classical music—I still feel foolish acknowledging that I only learned about pianist Jeremy Denk recently. He’s a fantastic musician (I’ll mention a couple of recent recordings in a moment) and also a remarkable writer. His blog Think Denk dispenses his erudition and his lucid analyses in entertaining, nondidactic ways, mixing his real-life adventures and his musical discussions.
