The Slaughterhouse is the thirtieth studio album by American recording artist Prince. It was released on March 29, 2004 by NPG Records. The album was released as MP3s through his website, NPG Music Club. The album's title comes from the first line of the song "Silicon", "Welcome 2 the slaughterhouse". The tracks consist of material previously available on the same website back in 2001, although some may have rearrangements of music and/or lyrics. "2045: Radical Man" was released on the soundtrack of Spike Lee's Bamboozled in 2001. "Peace" and "The Daisy Chain" were released as limited edition CD singles during Prince's 2001 Hit n Run Tour.
