If music be the food of love, sing on, sing on, sing on ... (Shakespeare)
The audio samples give an three-dimensional hearing impression of a BAS recording. In spite of quality losses through mp3 compressing the original material the spatial auditive experiences are substantially preserved. This becomes particularly obvious in case of the demo 3, where the audience is encircled by six percussion sets.
To reproduce the full spatial experience semi-open dynamic headphone should be taken. But also a good conventional stereo system provides a comparable auditory impression.
