Schulze explained the impetus for this album: "I have wanted to work with Lisa Gerrard since the days of Dead Can Dance, but I never had an opportunity for such a collaboration. It's also not so easy to reach her on the phone." Reciprocally, Gerrard said: "I know Klaus Schulze since Tangerine Dream. He is amazing, I mean, his work is sympathetic to a soul journey and has been for such a period of time."
Schulze prepared 300 minutes of music and scheduled 6 days with Gerrard for her to come to Hambühren: as Gerrard explained, "The important thing for me when I work with someone is that I go and listen to his music. All I did was go and improvise." The whole recording was actually done in two afternoons (on day 2 and 3) and half of the material was selected for the album. Schulze concluded, "Many people think good music has something to do with sweat and hard work, and it needs to last for months. However, my opinion is that if this is the case, the music is bad. Because if you are on the ball then you're just playing your best stuff."
