"Invaders Must Die" is the eighteenth single released by the British electronic band The Prodigy. It was released from the band's website as a free digital download on 26 November 2008. It was the first single from the album Invaders Must Die. The download was announced on 24 November, in a newsletter sent to fans, and first aired on Zane Lowe's Radio 1 show as his 'Hottest Record in the World' on 26 November. The song was co-produced by Does It Offend You, Yeah?'s James Rushent. Liam Howlett described this to the Dubai edition of Time Out as: "a very abrasive-sounding electronic track, kind of different to anything we've done before." Although not being a commercial single the track charted at 49 in the UK Singles Chart on 1 March 2009, whilst the Chase & Status Remix reached 53 in the Australian Aria Singles Chart and 7 in the Aria Dance Chart. On 30 November 2009 the re-amped version by Liam was released as an EP with the B-side Mescaline, and Thunder remixes.
Invaders Must Die is the fifth studio album by English electronic dance music group The Prodigy. The album was released on 23 February 2009 on the band's new record label Take Me to the Hospital, and was distributed by Cooking Vinyl.
The album was a commercial success, faring better than Always Outnumbered, Never Outgunned. In contrast to the commercial performance, critical reaction to the album was mixed. It has spawned four singles, including the title track, "Omen", "Warrior's Dance", and "Take Me to the Hospital".
Recording began in February 2006, shortly after the release of Their Law: The Singles 1990–2005, and ended in November 2008. Some of the songs recorded for the album, such as the synthesizer-led "Colours" were written before the release of the group's fourth album, and early versions were showcased in live performances. Liam Howlett conceived the album musical direction as a mashup of their previous albums. The new album was set to be released in summer 2007, but when the album's release date was postponed to the "first quarter of next year [2008]," the band had conceived over 25 ideas while completing production on certain tracks and writing lyrics.
