About Luciano Berio: Luciano Berio is noted for his experimental work (in particular his 1968 composition Sinfonia and his series of virtuosic solo pieces titled Sequenza) and also for his pioneering work in electronic music.
The relation between practical and spiritual spheres in music is obvious, if only because it demands ears, finger, consciousness and intellect.
In music, as I find myself forever saying, things don't get better or worse: they evolve and transform themselves.
