Swerving a little from the main thread and onto Steve Reich.I can take or leave most of the work of his that I've heard but there's one piece, called Different Trains, which, when I heard it first on Radio 3 I just found absolutely stunning and unforgettable.You probably wont want to risk another 20 minutes of your life wasted Mr MtheGM but I'd give it a go if you can find a recording somewhere.And its definitely "about" something.
