A charming and deeply funny memoir of musical obsession, A Devil to Play is the story of Jasper Rees, a man who unearths his childhood French horn, and begins a quixotic but obsessively serious challenge: to play a Mozart concerto—alone—for a paying audience within one year’s time. It’s an endearing, inspiring tale of perseverance and achievement, relayed masterfully, one side-splittingly off-key note at a time.
