Beyond the sessions for Head First, the duo had spent a week in Los Angeles in 2009, blessing pop superstar Christina Aguilera with some retro-futuristic sounds for her upcoming, electro-heavy fourth album Bionic. Although whether the track will be included is anybody’s guess.

“We don’t know what’s happening with it,” says Goldfrapp. “We don’t know whether she’s having an album out and we don’t know if the track’s on the album. We know nothing.” “She was very sweet. Very professional, really on… She knew exactly what she wanted. She was really articulate about what she was trying to do. Just seemed really in control,” adds Gregory. “We got the track to a certain point. But we haven’t heard anything since. It kind of needs finishing.”

When asked what the Goldfrapp/Christina collaboration sounds like, Gregory exclaims, “I don’t remember!”

“Not that good as far as we’re concerned, because it needs some work,” adds Goldfrapp. “So we fucking hope it isn’t going on the record, because it ain’t finished!”
