"Waiting" is the first single of British progressive rock band Porcupine Tree, released in May 1996. It came in two formats: a regular CD and a 12" vinyl. At the time, the single was intended to promote the forthcoming album Signify. The song is divided into two parts, the second one being an instrumental follow-up. Waiting is considered the first Porcupine Tree single for its length, since Voyage 34 and Voyage 34: Remixes are singles of around 30 and 40 minutes respectively that would fit better in the category of EPs. The song entered the UK Indie Chart, attracting airplay all over Europe. Porcupine Tree contributed an edit of "Waiting (Phase Two)" to the soundtrack for Paul Spurrier's movie Underground, whereas the credits erroneously listed "Waiting (Phase One)".
