• The Sinfonia of London, if any reminder is needed, has had two lives: as a recording orchestra in the 1950s with at least 300 film soundtracks to its name, including Alfred Hitchcock’s Vertigo; and as a special projects orchestra, with an emphasis on recording, relaunched in 2018 by the British conductor John Wilson. Players, several with principal roles in other orchestras, meet a few times a year. The description may make it sound like a standard freelance band. Instead, it is fast becoming one of Europe’s elite orchestras.
