I don't know, to me, he doesn't really set the record "straight." He doesn't say there was no meddling. It just came from Kevin Shirley, not the label directly.
I'm kind of with Blob, I don't really see a contradiction between this and what we already knew.
Yup, I agree too. JP's comment is pretty much the story we had from MP, just a different perspective.
The FII Demo liner notes clearly indicated, by MP, that the direction of the album was more of a straight-forward sound. So JP is 100% correct; the label had nothing to do with the overall intent of the album. As Blob said, they did write a bunch of songs that were rejected, so that was label influence. But in no way did their interference impact the writing. JP did mention Shirley's influence, and that was clear. The splitting of BMS/half of HK, cutting pre-chorus of HY, altering verses and chorus of TAMP, and YOM=YNM.
But really, how much really was changed? NM, PS, LITS, ToT, AL & JLMB all were pretty much exactly as they were demoed if I recall. LITS had one verse or something changed. TAMP still has the same melodies, just underlying instrumentation is different. HY was clearly made shorter to probably appeal to mainstream, but the song sounds the same. BMS/HK IMO actually sounds better, as the second half of HK was new and incredible I feel. But I get it, MP wanted the song as a straight-forward heavy song with a break in the middle.
YNM is the only true example of a complete change. But take that further… WHO wasn't involved with that? Who was?
I think what we have here is again, a different perspective. MP and JP both gave similar accounts, but their outlook was different. MP was absolutely negative about the rejection of songs, and some cutting, long process, and ONE song being partially re-written. JP was rather positive on the experience, with Shirley the producer being involved with cutting, as they do. But the band wanted a more straightforward approach.
So what we half is glass is half full/glass is half empty, but it's still a glass that is 50% occupied.
