On 11 March, the band's debut album, Blackened Sky, was released to generally positive reviews. It was around this time that the band began touring extensively, including supporting Weezer on 20 March at the Barrowlands in Glasgow. On 15 July, the fourth single from the album, "Joy.Discovery.Invention", was released as a double A-side with a newly recorded song called "Toys, Toys, Toys, Choke, Toys, Toys, Toys" (which would later also appear on their next album The Vertigo of Bliss). They toured as part of the Kerrang tour in 2001 alongside Sunna and Hell is For Heroes, followed by their first UK wide headline tour later on in the year. In 2003, the band retreated to the Linford Manor recording studio in Great Linford, Milton Keynes, England, to record the follow-up to Blackened Sky. On 24 March, a new single was released called "The Ideal Height", followed by a further new single "Questions and Answers" on 26 May.

After touring relentlessly for The Vertigo of Bliss, the band retreated to Monnow Valley Studio in Monmouth, Wales to record a follow-up album. As with the previous album, two singles were released before the actual album: "Glitter and Trauma" and "My Recovery Injection" on 9 August and 20 September respectively. An additional digital download was also released on 31 May, called "There's No Such Thing as a Jaggy Snake".
