It began a few days back. Via his social media accounts, Oren Ambarchi began posting a series of remarkable, candid photos of Alvin Lucier, marking their tour of the composer’s works through Asia – little kernels of joy threading their way into the world, followed by others taken by Crys Cole and David Grubbs. Each appearance made my day, but served as a painful reminder that, in the endless struggle to stay abreast of reviews, I had failed to write up the stunning four LP box set of his works, issued by Züricher Hochschule der Kunste in late 2017. Given how remarkable and timeless it is, there is no such thing as too late.
