set up their own label Transmission

During 2003, Porcupine Tree set up their own label, Transmission, with an online store hosted by Burning Shed record label. The first release on the Transmission label was a studio session recorded for XM Radio in Washington, DC, followed in 2004 by a recording from Polish radio in 2001. The band used the label to issue supplemental content, such as EPs, demos, and live recordings. Additionally, a reissue/remaster campaign also began in 2003, with many of the early albums expanded to double CDs. These reissues included re-recorded/remixed double-CD versions of the Up the Downstair , The Sky Moves Sideways , and Signify albums, and the reissue of Stupid Dream and Lightbulb Sun , both consisting of a CD with a new stereo mix of the album plus a DVD-Audio with a 5.1 surround mix.
