Review: SCO/Manze, Usher Hall, Edinburgh, Keith Bruce, four stars: Star billing for this week’s season concert from the Scottish Chamber Orchestra with Principal Guest Conductor Andrew Manze went to baritone Roderick Williams. At 60, with a diverse hinterland of music-making in recital and on the opera stage, at celebratory events like the recent Coronation and as a composer, Williams probably qualifies for National Treasure status.
