Catatonia were an alternative rock band from Wales who gained popularity in the mid-to-late 1990s. The band formed in 1992 after Mark Roberts met Cerys Matthews. The first major lineup featured Dafydd Ieuan of Super Furry Animals on drums, Paul Jones on bass, and Clancy Pegg on keyboards. With this line-up the band recorded two EPs, For Tinkerbell and Hooked.

Pegg was fired prior to work on their first studio album, Way Beyond Blue, and during the recording of the album the band was joined by drummer Aled Richards, replacing Ieuan, who left to focus full-time on Super Furry Animals. During the live promotional appearances for the album the band was joined by guitarist Owen Powell. This latest incarnation of the band lasted until its dissolution in 2001. The single "You've Got a Lot to Answer For" received radio airplay and became the band's first top 40 single in the UK Singles Chart in September 1996. Their breakout success came at the start of 1998 with the International Velvet album and the release of the single "Mulder and Scully" some two weeks apart. The album went to number one in the UK Albums Chart, and sold more than 900,000 copies being certified triple platinum by British Phonographic Industry, while the single reached number 3 in the UK Singles Chart, the highest any Catatonia single would chart.

The follow-up release, "Road Rage", reached number 5 in May, and was nominated for best song at the Brit Awards and the Ivor Novello Awards, winning at the Q Awards. The title track of the album International Velvet received additional attention, and the band performed it at the opening of the opening ceremony of the 1999 Rugby World Cup on 1 October in the Millennium Stadium in Cardiff. While in Catatonia, Matthews collaborated with Space on "The Ballad of Tom Jones" in March 1998 and with Tom Jones on a cover of "Baby, It's Cold Outside" in December 1999. Their final top ten single came in April 1999 with "Dead from the Waist Down" off the following album, Equally Cursed and Blessed. Rumours began to circulate about a breakup, but a further album, Paper Scissors Stone was released in 2001 following a two-year break from live performances.

Matthews' drinking had long been reported in the tabloids and gossip columns, and she entered rehab in mid-2001 for drinking and smoking. The tour to support Paper Scissors Stone was cancelled, and a month later, the band announced that they were breaking up. Matthews has subsequently released solo albums, while Powell has become a radio presenter and joined the supergroup The Stand to release a charity single. Critics have highlighted the use of metaphors in Catatonia's work, as well as comparing songs to poetry. Writing duties had been shared across the band, although had been led by Matthews and Roberts. They disagreed with being labelled an indie band, with Powell saying they had only ever sought to write pop music. The band were considered a key band of 1990s Cool Cymru.

The story that Catatonia were formed after Mark Roberts spotted Cerys Matthews busking in Cardiff in 1992 was an invention for the media in order to give the band a newsworthy biography. While the duo did go busking, they did not meet this way. Matthews had been a fan of Roberts' previous band Y Cyrff. They began dating as well as writing songs together at the end of 1991. For five years after this they remained in the relationship, many aspects of this being played out publicly in their lyrics. They took the name of the band from Matthews' experience working in a mental health facility as well as the novel The Doors of Perception by Aldous Huxley. They believed it to mean a sense of extreme pleasure and sleep, and wrote the song "Sweet Catatonia", subsequently naming the band after the song. As Sweet Catatonia, Matthews and Roberts recorded a series of demos at the city centre youth project in Cardiff, nicknamed "Grassroots".

Roberts and Matthews routinely encountered Owen Powell during this time, who played guitar in the band Colour 45 and was working as a Welsh teacher at Brynteg Comprehensive School. Both bands entered a band competition to play at the Cardiff Bay Music Fiesta, and while Colour 45 came tenth and was given a place on the bill, Sweet Catatonia placed 45th. Roberts and Matthews hired a drummer, Stephen "Frog" Jenkins from the band U Thant, and continued to record bilingual Welsh/English tracks. The band began to play live, with Matthews and Roberts busking to support their income. They were spotted by the girlfriend of the lead singer of the band The Pooh Sticks, who thought that Matthews would make a good female voice for the group. But after seeing Sweet Catatonia perform, the band members did not agree and so Matthews remained with Catatonia. Further recordings were made, with Guto Pryce joining the trio. This session included the track "Gyda Gwen" which attracted the attention of Rhys Mwyn at Crai Records.

The band line up changed as they signed to Crai, with Jenkins and Pryce departing for other projects. Mwyn arranged for Matthews and Roberts to be joined by Dafydd Ieuan of Ffa Coffi Pawb on drums, former Y Cyrff member Paul Jones on bass, and Londoner Clancy Pegg (who had befriended Roberts and Matthews after moving to Cardiff) on keyboards. It was at this point that the band shortened its name to "Catatonia". Mwyn used his contacts to get Catatonia onto Welsh language television, and strove to move their live performances away from Cardiff so that they were not simply playing in front of their regulars the entire time. They had their first overseas gigs in Germany, support Mwyn in his punk band Anrhefn. Catatonia were hired by political party Plaid Cymru to headline a Welsh language concert at Builth Wells in August 1993, but they performed in both Welsh and English.

Despite being signed to Crai, this was more as promoter than as a record label itself. It was only when Roberts suggested that Catatonia record some extended plays (EPs) after two months with the label that Mwyn made the arrangements. The first, entitled For Tinkerbell, had a cover photo taken by Roberts and Matthews' housemate Roland Dafis. Mwyn successfully got the record on BBC Radio 1 after sending a copy to radio presenter Mark Radcliffe. After Iestyn George heard the release, the journalist named it as the record of the week for the magazine NME. For Tinkerbell contained some early tracks, including a version of "Sweet Catatonia". Matthews later explained that while she had liked the songs on the EP, she felt that she was not good at performing live at the time. They signed to Nursery Records to release the single "Bleed". Catatonia's first national interview was published following the release of "For Tinkerbell", a 300-word piece appearing in Melody Maker.
