"Computer Blue" was originally recorded at The Warehouse in Minneapolis with The Revolution a day after "Let's Go Crazy", and was later overdubbed at Sunset Sound in Los Angeles in August 1983. Prince, along with Wendy & Lisa and sound engineer Susan Rogers, set about doing further work on what would later end up being placed on the album "Purple Rain", albeit in a very heavily edited form. The song begins with spoken lyrics by Wendy & Lisa which suggest a dominatrix-type relationship. The song then explodes into an experimental rock number with screaming, heavy synths, distorted guitars, and lyrics about the relationship between humans and computers. The released version has only one verse; the version that debuted at the First Avenue nightclub had a second verse, as did the song when it was originally recorded, and this original recording (later released as the "Hallway Speech" version) lasts for over 12 minutes.
