In April 2005, in the middle of the Hopes and Fears tour, the band began recording "Under the Iron Sea" with producer Andy Green, who worked with them on "Hopes and Fears". The band later recruited Mark "Spike" Stent for mixing duties. Recording took place in Helioscentric Studios, where "Hopes and Fears" was recorded. Additional recording was done at The Magic Shop Studios in New York.
