Porcupine Tree release that equals Lightbulb Sun?

My first experience with PT was 'Up the Down Stair' from about 1992, which was also about when I encountered it. Then 'Voyage 34', 'Staircase Infinities' and then the 'new' album, 'Sky Moves Sideways'.

These albums were right up my alley- a lot in common with the happier, trippier Floyd pre-Dark Side, with some strong Kraut-rock influences, yet still its own aesthetic. I like them so much that I forgive anything that has followed (most of which I enjoy a lot). 'Signify' brought a new sound for the band, less of the amazing jamouts and more harmonized vocals (usually with dark lyrics). Later albums confirmed that pathway, more song/pop oriented, but the roots are plainly obvious to me with any of their work to date.

The recent re-releases of Signify and Sky Moves Sideways include second discs containing primarily studio jams which would later evolve into the released versions of the albums.

Trippy and hypnotic with little if any vocals. I often listen to the jams rather than the official releases.

PT also have re-released earlier recordings. I suspect they include jams as well, but I'm not certain.

FWIW its worth it to look for the earlier vinyl if you can find it. At least in the case of Voyage 34 and Up the Downstair, the originals sound better.

For those who like Lightbulb Sun, check out Blackfeild which is a side project of Steve Wilson and Aviv Geffen. The songs are more straight ahead like Lightbulb Sun but still rock out. A great must have for Steve Wilson fans,

I watched the Blackfield DVD last night again. Good stuff.
