This Wednesday, London Sinfonietta presented Luke Bedford: In Portrait – a concert with a format that seemed almost too good to be true. In a short programme combining Luke Bedford’s Wonderful No-Headed Nightingale (2011–12), Renewal (2012–13) and Gérard Grisey’s Périodes (1974), conductor Sian Edwards and the London Sinfonietta beckoned us into a world of shifting soundscapes.
