Adieu. The New Yorker, May 4, 2009.
A Finnish TV crew was following Salonen on the day of his first encounter with the L.A. Philharmonic, in 1984. The footage can be seen on the orchestra's Celebrate Salonen site; click on "Video" and then scroll down to "One Minute, Maestro." I believe you can actually see a couple of veteran players rolling their eyes at the stripey-shirted apparition before them. But he establishes his authority at once. Timothy Mangan has excellent photos from the final concert on his blog: see especially 1, 2, 3.
