During a Nine Inch Nails concert in Lisbon, Portugal, a USB flash drive was found in a bathroom stall containing a high-quality MP3 of the track "My Violent Heart", a song from the then-unreleased album. A second USB drive was found after a concert in Barcelona, containing the track "Me, I'm Not". Following the release of "Year Zero" the focus of the tour shifted towards debuting and promoting tracks from the new album. While some of these songs were performed by all 5 band members as conventional guitar-driven rock songs, two of them ("Me, I'm Not" and "The Great Destroyer") were played by Reznor, guitarist North and keyboard player Cortini as a 3 piece, using a combination of live guitars and pre-programmed samples triggered onstage with computers and manipulated in real time using Ableton software.
