But what happens when a confession never comes, and a secret festers instead in collective silence? That’s the starting point for Festen, Thomas Vinterberg’s 1998 film, which was adapted into an award-winning opera by Mark-Anthony Turnage and librettist Lee Hall last year. There’s a fair bit of plot to a work in which incestuous child abuse is exposed during a patriarch’s 60th birthday party, but it’s the atmosphere that lingers, stylishly distilled in Turnage’s new Festen Suite – receiving its UK premiere here from the BBC Symphony Orchestra and Sakari Oramo. It’s cleverly made and musically satisfying on its own terms, without the dramatic scaffolding of the opera. Soloist Guy Johnston stayed scrupulously, sensitively faithful to the composer’s conception: the orchestra’s equal, often a part of the texture rather than its focus.
