Document 3: Up the Downstair: Up the Downstair is the second studio album by British progressive rock band Porcupine Tree, first released in May 1993.

In 2005, it was partially re-recorded, fully re-mixed, remastered and re-released along with the "Staircase Infinities" EP as a double album. The re-release contains a new mix by Steven Wilson, along with recorded drums by Gavin Harrison that replace the electronic drums of the original version.

It's also one of few Joy Division songs with two distinct guitars playing, one distorted and one a clean electric guitar picking notes from the guitar chords.
