 Finally, ten tracks were chosen for their next studio album, "Up the Downstair" (1993), which "Melody Maker" described as "a psychedelic masterpiece".At the end of 1993, Chris Maitland joined the band for live shows and would later record some drums and percussions for three songs of Porcupine Tree's third studio album, "The Sky Moves Sideways" (1995), an album that made the press refer them as the "Pink Floyd of the nineties".They did not record as a full band until "Signify" (1996), the first Porcupine Tree album to be performed entirely by the four members.
