The band revealed last month that they are returning to the studio with Eno for their upcoming fifth album this spring, which frontman Chris Martin later announced he wants to release before Christmas.
The veteran producer, who helmed Coldplay's 2008 album Viva La Vida Or Death And All His Friends, told BBC 6 Music that he has forced them out of their comfort zones on the record.
"It's not rocket science, and it's not Svengali-ism either," he explained. "It's not some attempt to subvert the band, but just to see what other possibilities are lurking within them that might not come out within their normal working situations."
Describing the group's latest tracks, he added: "It's quite different from anything they've done before, I think, so far anyway. I don't know how it will end up being, but it's very fresh."
