Krzysztof Penderecki, who died on March 29th at the age of eighty-six, was a composer who made a huge impact on me when I first heard his classic pieces of the sixties and early seventies. Alas, I found the vast majority of his later music to be of much lesser interest, though I attempted many times to warm to it. I turn the microphone over to Tim Rutherford-Johnson, who has studied Penderecki's music in depth.
