Porcupine Tree release that equals Lightbulb Sun?

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.
