One word: Navigator. Probably better than a 3, although in PT context, not really a standout release. The gem on this is perhaps one of the more underrated instrumentals in Porcupine Tree's repertoire.
This is my favourite porcupine tree disc. There are better albums then this EP in terms of songs and production. While I don't think it is the BEST album they have produced it is my favourite listen of them. Clocking in at around the 30 minute mark, it packs in much musical territory. I won't go into song by song detail but this is a half hour of my life wasted in a psychedelic daze. Thank you Steven Wilson for what you deem not good enough to make the record.
