I like the idea of a kind of eternal music, but I didn't want it to be eternally repetitive, either. I wanted it to be eternally changing. So I developed two ideas in that way. 'Discreet Music' was like that, and 'Music for Airports.' What you hear on the recordings is a little part of one of those processes working itself out.

My ancestors had to keep their customs secret for fear of death or persecution, so it's common to be secretive and discreet about Regla de Ocha. But it's my family's spirituality, so I don't want to keep it secret.

The fact that there were discreet channels of communication established with Iran in 2012 is something that we confirmed publicly.
