I reversed and sped up the audio from this clip shared across Porcupine Tree's social media platforms. It was sped up 5X. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-oLy42_oe8Cw.html #PTCC
This is only a theory but the picture of the face in the original video could possibly be the boy from fear of a blank planet growing up. Fear of a blank planet the Continuing Story?
Whoever is saying 'You are' sounds a bit like Maynard James Keenan. Might be wishful thinking but imagine if MJK guested on a future Porcupine Tree release
There's another version of this snippet that's sped up to a slightly different degree where the voice sounds a tad different so therr's no telling who this is really.
