In 2017 the Berlin Philharmonic released its John Adams Edition, taken from concerts by the orchestra. Now it has done the same with its archive of performances of Unsuk Chin’s beguilingly coloured music, recorded between 2005 and 2022. It’s a collection of six works, handsomely presented and scrupulously documented, and including a Blu-Ray Disc with videos of all but one of the performances, as well as an interview with the composer.
