High Quality Content by WIKIPEDIA articles! "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 2 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 EP's.
