Razorlight were formed in 2002 by singer-songwriter Johnny Borrell. At the start of their career Johnny Borrell's new outfit began by supporting The Libertines at various venues (including 333 in Old Street) where a young A&R scout, Justin Cross, found them and put them in Liam Watson's Toerag Studios where he produced the tracks "Rip It Up", "Rock 'n' Roll Lies" and "In The City" alongside John Fortis. Off the back of these tracks the band (now named Razorlight) began getting serious A&R heat due to the songs success on radio stations such as John Kennedy show on XFM.

The band then became very popular on the London music scene. Large demand caused the band to play extra shows, including a 7,000+ capacity gig at Alexandra Palace. The album was heavily marketed in the UK.

Following the release of their successful debut album Up All Night in summer 2004, drummer Christian Smith-Pancorvo left the group and was replaced with Andy Burrows.

Up All Night was re-issued in April 2005, including the previously unreleased single "Somewhere Else", which peaked at Number 2.

In July 2005, the band performed at Hyde Park, London as part of the Live 8 series of concerts. However, the band came under fire for being the only band that did not donate their extra revenue to charity. The band subsequently claimed that due to their "fledgling status", they were unable to make such a commitment.

Razorlight supported Queen + Paul Rodgers on July 15, in front of 60,000 people. This gig had been rescheduled following the July 2005 London bombings. In December of the same year, they supported Oasis, at Cardiff's Millennium Stadium. They also supported The Rolling Stones at their gigs in Cologne and Paris.

During the Christmas season the band played an intimate show at the Railway Inn in Winchester. They were supported by up and coming London band Captain Phoenix, who are fronted by drummer Andy Burrows' younger brother Ben.

The band played their biggest tour to date in October-November 2006 and also supported Richard Ashcroft in his homecoming gig at the Lancashire County Cricket Club on June 17.

In November 2006 the band had to be hospitalised after traces of radioactive poisoning was detected on their plane. Their British Airways return flight from Moscow was a scheduled route used by Russian ex-spy Alexander Litvinenko.

In 2007, Razorlight were nominated for two BRIT Awards - one for 'Best British Band' and the other for 'Best Song', "America". They were also nominated for two NME Brit Awards for 'Best Band' and 'Best Album'.

They played Reading on 24 August, and Leeds on 25 August 2007. They also played the Main Stage on 19 May in Preston for Radio 1's Big weekend alongside bands such as Kasabian and the Kaiser Chiefs.

On July 7, 2007, Razorlight performed at both the UK leg of Live Earth at Wembley Stadium, London, and T in the Park in Balado, Scotland.
