'''''The Slip''''' (also known as '''''[[Halo numbers|Halo 27]]''''') is the eighth and latest studio album from Nine Inch Nails. It was released as a free download on May 5, 2008, and contains the previously released Web-only singles "[[Discipline]]" and "[[Echoplex]]."
The album is available for download in a variety of formats, including MP3, lossless FLAC and high-quality WAV files. When playing the MP3 files in an MP3 player a different piece of artwork is displayed for each song, as was the case with ''[[Ghosts I–IV|Ghosts I]]''.
The Slip sounds quite lighter then anything Nine Inch Nails has ever released before, and surpasses Year Zero on raw noise. The album is very dance-friendly.
