According to the blurb on the Youtube video for the new song (Harridan), it will be called Closure/Continuation, and will be released 24 June 2022. The last PT album, of course, being The Incident in 2009.
Here: have some new Porcupine Tree, because I like you and want you to be happy.
I haven’t thought about PT for a good decade - what a blast from the past. Excited they’ve “re-banded” and are coming out with new material. Thanks for this!
