This is what I wrote in iComp, November 14, 2007:

“Some time ago I sent Petra some music to sing on. She asked me to wait a bit because she had one of her art exhibitions and would be busy for a while.
A few days later, I received from Petra this pure gem in my mailbox.
I feel blessed when I am allowed to be part of the musical world of someone I admire.
This is a song with Petra singing and me on instruments: just an excuse to make Petra sing with her unique voice. Thank you, Petra.”

It was 17 years ago.
Before social media.
iComp was just a small chat window and a lot of listening. In that little chat window a LOT of things happened. People were born, some people died, people got divorced, people got married....
I only remember two couples of iCompers who got married, and Petra was part of one of those two couples.
Petra was like something out of a Bergman movie, transparent, made of sky and golden barley, while my music was rock, blues, Latin and stinky Macoco's Bar, until I sent her this strange chord evolution that she was kind enough to not only improve it, but make it unforgettable with her voice.

17 years later, I sing it in the shower, whistle it in the street, remember every word in that precious language she was kind enough to translate for me, for us.

Gracias Petra.
