I opened the jacket, and looked for a note, nothing. I looked in the packaging. Nothing. So I decided to put the CD into the player. It was incredible. The rolling sound, never changing, only shifting (or 'calm, still and deep, yet always evolving' as the blerb says) . Incredible. It is what I have been searching for, but not knowing I needed.
Who sent it to me? Was it even meant for me? A small footnote in the blerb says "...the record is often chosen for use during childbirth and is a semi-permanent fixture in some maternity hospitals". So I took that as definitely meant for me.
I have no friends or living family in the UK. So the mystery remains, but in the meantime, I am most certainly enjoying the music!
