The album was preceded by a single, "The Box", starring the actress
Tilda Swinton in the single's video. Paul Hartnoll told the
NME that the song was based on a recurring dream he had about the discovery of a mysterious wooden box in the Welsh countryside, but that he would always wake up just at the point he was opening the box, so he never found out what was inside it. Environmental concerns are one of the major themes of the album: "Dŵr Budr",
Welsh for "dirty water", was inspired by the
Sea Empress oil spill environmental disaster which took place just off the southern coast of Wales in February 1996. Paul Hartnoll told
Vox, "We came up with the chords that start the track, and I thought: 'That sounds nice, it sounds like the sea'. And it reminded me of staring at the murky water in
Brighton from one of the sea-breakers, thinking, 'Uh!
God!' So I thought: 'Let's make this track about the horrible dirty water that everybody has to swim in. The song was written and recorded in a single day before the album's scheduled mastering. An early version of the album's opening track "The Girl with the Sun in Her Head" was recorded for the
Hackers film soundtrack, but was not included in the film. The final piece was entirely recorded using electricity provided by
Greenpeace's mobile
solar power generator, Cyrus. It opens with an emulated heartbeat sound created with an ARP 2600, which serves as bass and develops into what many critics hold as one of Orbital's most accomplished pieces. (and included on its later soundtrack album); it is also featured on the soundtrack to the film
π. "Adnan's" is a longer version of the track originally included on 1995's charity album
The Help Album, benefitting
War Child. Paul Hartnoll said that "the name comes from the sympathy story of the day on the news about a family evacuated from the former
Yugoslavia. The father had to stay behind to work, and his 16-year-old son decided he had to go back and stay with him. He felt he couldn't leave him on his own. After a few days the son, Adnan, got blown up and killed." The two-part closing track "Out There Somewhere?" deals with another of the Hartnolls' preoccupations, science fiction and
extraterrestrials. Paul said, "I was looking for samples from this TV programme about the way people react to
UFOs. It's not about UFOs, it's about that spiritual gap being filled by the aliens coming down to save us... Then the second half is the euphoria of what the person
wants to feel when they've been abducted." ==Artwork==
