I have an old friend who, when he is sitting comfortably in our lounge, and a truly classic piece of music comes on the stereo, closes his eyes as he listens. I think he sways a little too. He certainly zones out. He escapes the confines of our simple human surroundings, switches off the world around him, and allows his mind to soar to lofty and beautiful places in which the depth of his appreciation knows no bounds. He transcends those in the room who nod in his direction and snigger, and he rises to a place above us all.
