Trinity Laban composer Alexander Ling unveiled a new work, Mandala, in a concert of pieces by Wagner, Webern and Bruckner played by the conservatoire’s symphony orchestra at Blackheath Halls. Mandala, inspired by the oriental life-symbol, is a minimalist joy and was given added potency by being juxtaposed with the soaring orchestrations of Ling’s three musical forebears. A brilliant debut by a man I expect to hear much more about in the future.
