I was at that gig, wonderfully self indulgent stuff.The worst gig I ever went to was one of theirs back in the early noughties at Manchester Academy. At one point all the lights were turned off, the guitarist laid on his back and played a guitar solo for, what felt like, 10 -15 minutes. Not one other person needed to be in that room and he'll have still had the time of his life.
Not listened to a note of theirs since but I'm intrigued to know how they've evolved so will give it a listen
