Speaking in an interview with Pitchfork magazine, Spaceman said: "There’s a lot of stuff that we recorded that I still haven’t heard yet."

The producer also talked in depth about the creative period which led to Ocean dropping two of the hottest albums this year. Spaceman, who has worked with everyone from Miles Davis and Sly Stone to Sun Ra and Aaliyah, said: "We had like 14-hour, 15-, 16-hour sessions. We’re creating continually. So something may happen, and [Frank might] say, ‘Oh, that’s nice, let’s try this here.’ So it winds up becoming a thing, and then I wind up doing a lot of different kind of textures."

"It wasn’t defined: ‘OK, this is 'Endless',’ or ‘this is 'Boys Don’t Cry' or 'Blonde'’ or whatever the working titles were. I call it just one giant, long record."

On working with Ocean, Spaceman said: "Frank was cool. He’s a cat. He’s a creative kind of guy that’s very introspective. And he’s got big ears. He hears a lot of things. He’ll hear something and say, ‘Ah, yeah, that’s good.’ We wind up finding the elements that work in a particular sequence of sounds."

The news comes as Frank Ocean breaks his long radio silence since the release of Blonde to speak to Zane Lowe for BBC Radio 1. The Evening Standard confirms that the presenter recently took a 48-hour trip to Tokyo to meet the elusive musician and the interview will be aired on Zane Lowe's BBC Radio 1 show.
