NINJA 2009 Tour Sampler (stylized as NIN|JA on the cover) is a free compilation by Nine Inch Nails, Jane's Addiction and Street Sweeper Social Club as part of the Nine Inch Nails and Jane's Addiction 2009 NINJA tour.[1] It was released on March 20, 2009 for free, on the tour's official website. Both of Street Sweeper Social Club's songs that appeared on the album, "Clap for The Killers" & "The Oath", later appeared on their self-titled album. The two Nine Inch Nails tracks, "Not So Pretty Now" and "Non-Entity" were both originally recorded during the With Teeth sessions, but did not make it onto the final record.[2] The two Jane's Addiction's songs are re-recorded versions of songs that had originally only live versions, from the band's first official record.[3][4]
