There is an interesting David Rhodes interview on the GuitarGuitar website about the current tour
https://www.guitarguitar.co.uk/news/141879/
He encapsulates PG's attitude to the i/o release succinctly:-
GG: Right! So, this is the new - and somewhat unusually unreleased - I/O record we’re talking about. Are there three tracks released so far?
DR (David Rhodes): Yeah, there are six tracks out now.
GG: Oh, I’ve missed a couple! So, it’s an unusual thing for such a big act to be touring an album that isn’t out yet. Was that a deliberate thing, or just how things occurred?
DR: I don’t know, I mean, it seems like a slightly odd decision but Peter delights in being playful and quirky, I think. Actually, I think he’s also reached the time in his life when he doesn’t really give a fuck! (laughs) Which is fun! He’s just said, ‘Well, this is how I’m doing it. This is how I want to do it’.
Can't be clearer than that!
