Sir Colin Davis has died at 85. He had been in poor health for some time and I believe was hit particularly hard by the loss of his wife a few years ago.
He was a major figure in the Berlioz revival of the last 40 or 50 years. I assume he recorded all of Berlioz's orchestral and operatic works at least once; he is certainly among the go-to conductors for Berlioz. I also have him in Sibelius and a most graceful and charming recording of most or all of Mendelssohn's incidental music to A Midsummer Night's Dream.
My favorite story about Davis is that, as a wind player in the early 1950s, he was denied entrance to a conducting degree program because he wasn't a pianist. Given where he went as a conductor, the joke is on the degree program and that requirement.
He was a towering figure in British musical life, and will be greatly missed.
