Chatham, the man who rocks the minimalist canon like a hurricane, gathers up the City Of Light in the evanescent beauty of his latest piece, written for 400 guitars and performed live in the basilica of landmark Sacre Coeur, with an audience of 10,000 watching and 100,000 watching on TV. As the music shimmers, it offers a snapshot of eternity, an echo of a moment a thousand years gone, and a thousand years to come.
