Lostprophets were an alternative rock band formed in Pontypridd, Wales in 1997. The band was founded by vocalist Ian Watkins and guitarist Mike Lewis. Initially, Watkins played drums for the band, although its success only began when he transferred over to lead vocals. They have released several demos, none of which have been produced commercially, five studio albums, and fourteen singles. Their fifth and final studio album is titled Weapons, released on the 2nd of April 2012.

The first of these albums, The Fake Sound of Progressimg, was originally recorded for the meager sum of £6000 and intended as a glorified demo, but after catching the ears of several major labels, the band re-recorded and re-released the album on a much wider scale through Columbia Records. This resulted in a backlash against the band that was exacerbated by the four-year gap between their first and second albums. When the second album, Start Something, was finally released, the band achieved even greater success, entering the UK album chart at number five, and earning the band international popularity, most notably in the United States. Their third album entitled Liberation Transmissionimg was released on the 26th of June 2006 in the UK and entered the UK album chart at number one.

In April 2007 Lostprophets began the Final Transmission - the last round of touring of their current album with Aidenimg and Taking Back Sundayimg as the confirmed support. The bands played at huge venues such as Wembley Arena. The end the tour, on Saturday 26 May 2007, lostprophets performed at The Full Ponty festival at Pontypridd's Ynysangharad Park. Pontypridd is also the hometown of most of the current band members and so the festival was advertised as "lostprophets homecoming". Other bands at the festival included Reel Big Fishimg, The Automaticimg, The Blackoutimg, Gallowsimg and Kids In Glass Housesimg .Following the tour, the band hit the studio to record their fourth album which Ian Watkins is describing as a return to their roots with heavier punk influences. Watkins says "It will be a lot darker and a lot more intense. It'll have a completely different vibe to it … but it won't be like Converge or nuthin".

Their 4th studio album "The Betrayed" was released on 19 January 2010.

On 20 December 2012, lead singer Ian Watkins was charged with a host of offences involving sexual activity with minors. The band disbanded in October 2013. Watkins was later convicted and sentenced to twenty-nine years in prison, with six more on extended licence.
