Warning Sign

Chris Martin himself, the band's frontman, has commented that this song arose from a personal experience, specifically his breakup with Lily Sobhani, a live event producer. The separation occurred while they were promoting their first album, Parachutes. Martin has occasionally expressed a complicated relationship with Warning Sign, even feeling that the song portrayed him too favorably, when in reality it was written at a time when he himself admitted to having behaved inconsiderately. Guitarist Jon Buckland mentioned that it took him over a year to find his part in the song, eventually playing the maracas on the recording. A Rush of Blood to the Head, released in 2002, was Coldplay's second studio album and was recorded with Ken Nelson as producer, who also participated in the mixing along with other band members and Mark Phythian and Danton Supple. This album is distinguished by a greater use of electric guitar and piano compared to its predecessor, Parachutes. The band almost chose Warning Sign as the second single from the album, but the choice ultimately fell to The Scientist. The song also had appearances on the big and small screen, being included in the film The Last Kiss and in an episode of the series Buffy the Vampire Slayer.
