The singer told NME that the record will be called Pala, and is named after the novel of the same name by Aldous Huxley.
Macfarlane also revealed that tracks produced by Paul Epworth and Andrew Weatherall may be included in the album. He added that a portion of his writing for the record was undertaken in a remote cottage in Northern France.
He explained: "I just kept working, all day and into the night. After three weeks I was getting cabin fever but I had to focus, because the songs needed to get written. Did I feel under pressure from the rest of the band? Yeah, just a bit."
The group recently recorded a cover of Depeche Mode's 'Strangelove', which is used in the Frank Miller-directed advertisement for Gucci's 'Guilty' fragrance.
