This is an exceptionally fine reading of a testing concerto from a young British prodigy who has been unfussily maturing into a compelling violinist. She catches the sinuous ethereality of Sibelius’s vision, and the loneliness as well, but there’s plenty of passion where it matters and tremendous technical skill. The Bergen Philharmonic and Andrew Davis also offer a kind of Your Hundred Best Sibelius Tunes, including Karelia and Finlandia.
