I was at the Reading gig and there were 3 major issues;
(i) IB's vocals
He's always had a problem but this was the start of his vocals getting even worse. He has said that he started to have physical problems of hitting certain notes.
And if you've seen him since he's just getting worse & worse.
(ii) The introduction of keyboards
If their was any room for keyboards in Stone Roses it surely needed to be some kind of psychedelic sounds but Nigel is a jazz player. Playing jazzy chords with piano and organ just watered the sound down and made it go all cabaret
(iii) The dancing woman who came out for a couple of songs.
She was ugly and it all looked cheap.
The "hired guns" were actually multi talented musicians that could of pushed Stone Roses in a new direction given the chance.
e.g the guitarist Aziz, is playing for Steven Wilson now and that says all you need to know about his ability.
