A wonderful disc to relax to, and at the same time listen carefully to.  You can put it on and set the volume for background levels, and you'll be peacefully conveyed to a place where all is calm, tranquil and, in fact, harmonious.  At the same time, if your mind demands more stimulation all you have to do is lift your eyes and listen more closely, and you'll be stimulated by top-flight musicians, exploring new worlds of emotional expressiveness.
