Music, especially harp and voice, has the power to heal whether you are listening or participating in the making of it. The voice has the capacity to touch us in such an elemental way because it is literally the very first instrument. It is part of our physiology, human nature, and collective unconsious. It is the instrument of comfort and the angels in whatever belief system it crops up in. When choosing music to relax with, acoustic live music is best.
Canned music is like processed food.
It loses it's nutritional value through digital processing. It is literally reduced to numbers and spit out again. Live music is excellent because you are getting an authentic fresh interpertation and a shared experience with other audience members. This serves to facilitate a connection with the rest of humanity in a physical, emotional and harmonious way. The musical intent can come through in a pure fashion.
