The group, who were recently crowned winners of this year's Mercury Music Prize for their debut LP xx, gained praise from fans and critics for its space and sonic sounds.
Drummer Oliver Sim has since admitted that many noises on the album were the result of recording it in a converted garage.
He told the Daily Star: "The space in the songs came from the limitations that Romy and Olly had recording them. All they had was a multi-track recorder with room for four tracks.
"I [also] refuse to play live drums because so many bands have live drums. I don't think I could be as innovative on live drums."
The band also revealed that they become nocturnal when creating the record because they created better music in the evenings.
Sim added: "Once we started the recording we went into vampire mode, we like working when most people are ready to go to sleep.
"Things flow easier, emotions are high, everybody in my house was asleep so there were no disruption. There's a certain type of stillness at night that helps the hushed tone in our music."
