The Betrayed is the fourth studio album by Welsh rock band Lostprophets, released through Visible Noise and Sony Music on 13 January 2010.

Although the band initially wished to record a quick follow-up to 2006's Liberation Transmission, problems with labels and producers led to numerous delays.

Having started writing new tracks between tour dates in 2006 and 2007,[1] Lostprophets debuted several new songs live in 2007, including "Next Stop Atro City", "The Dead", "Weapon" and "For He's a Jolly Good Felon".

The band recorded demo tracks in then-drummer Ilan Rubin's garage in San Diego,[2] and album sessions with producer John Feldmann in Foxy Studios, Bel Air[3] in July.

magazine revealed six new song titles, including one ("Save Yourself"), which later appeared as a bonus track on Weapons, and four ("Credible vs Incredible", "The Mourning Reign", "What Seems to Be the Problem Officer?"

[8] The band also left their US record label, Columbia, also unconvinced of the quality of the new material,[3] around this time, with Sony Music Entertainment taking over their actions in the American market.

[7] Faced with such adversity, Lostprophets decided to take control of the record back, with bassist Stuart Richardson (who had produced the band's demo EPs in the late 90s[3] and the self-titled debut album for Attack!

[7][8] They continued writing in 2008, debuting eventual first single "It's Not the End of the World, But I Can See It from Here" (a title that had been mentioned since August 2007,[6] having been one of the first songs written for the new album in 2006[10]) and "Streets of Nowhere"[11] live, as well as a new version of "Next Stop Atro City".

[7][8] Rubin was invited by Trent Reznor to join the touring band for Nine Inch Nails in November 2008, and so left Lostprophets but not before tracking all of the drums and helping pen some of the music for the album.

[14] Former Beat Union drummer Luke Johnson joined Lostprophets around June 2009,[8] has filmed the videos for the album's first two singles[15] and has played live with the band since late August.

The website for the magazine Rock Sound subsequently revealed that the album had been delayed once more to early 2010, and that the first single is "It's Not the End of the World, But I Can See It from Here", due for release in October 2009.
