[3] It was announced in June 2009 that the album was being re-released as a deluxe edition, containing a bonus CD including b-sides from the original recording sessions and live versions of "99" and "Deathcar".

The album was written and demoed in Northampton at Alex Westaway's barn and then recorded in Los Angeles with producer Matt Wallace (Faith No More, Satchel, Deftones) in Spring 2007.

[6] Lyrically, the album is more of a "personal record" according to frontman Charlie Simpson, as opposed to Grand Unification, which was written as more of a social commentary with a concept based on the Japanese anime series Neon Genesis Evangelion.

[7] He stated that the end of his seven-year relationship whilst writing the album was the reason for this and songs "Deathcar" and "Unfamiliar Ceilings" were directly about the breakup.

The repercussions of it, a lot of the things that us a human race are doing at the moment – we're going to see the consequences in fifty years when we're all pretty much old and ready to pop our clogs.

[9] The band put a temporary microsite online as of 11 May where fans could sign up and download the single and accompanying video for free.

[23] Joe DeAndrea of AbsolutePunk.net scored the album at 83%, and praised the diversity of songs on offer: If you like the direction One Day Son takes with "Deathcar", you'll surely enjoy "H.I.P.

One Day Son closes with the relaxing "Unfamiliar Ceilings", featuring soft female vocals and a kick drum while lacking the big guitar riffs that are present in almost all of the songs in this album.

He went on to add, "Radio-friendly single '99' is weighty yet melodic, 'You and I' is a ripening attempt at a breathy serenade, while harder tracks like 'Tannhauser' throb with well-regimented aggression, threatening to pulverise anyone who might question the band's rock credentials".

[20] Q Magazine also rated the album 4/5, stating: "the intricate instrumental passages, multi-tracked vocal harmonies and pounding riffs hint at Muse-scale ambition and intellect".
