I do have to admit that I respect Gary for being so upfront with his opinion. I don't believe he was trying to 'bash' Hadrien; I think Gary was just being honest. That being said, I don't believe that it was necessary for him to be THAT honest.
It's pretty clear that Gary has a lot of respect for what Hadrien does, but it's also clear that the article contained some criticism of Hadrien's playing. Not harsh or mean criticism, but criticism nonetheless. I have to admit that I'm confused as to why Gary responded the way he did. If he wanted to offer some constructive criticism towards Hadrien, it would have been much more appropriate to do it in private rather than on a public drum forum.
I don't know about what other people here think, but to me it's bad form to criticize another musician publicly. Musicians (especially from the same band) share a bond of 'brotherhood' or whatever you want to call it. In my opinion, Gary's comments were probably unnecessary.
Why was it important that posters on an internet drum forum know what flaws in Hadrien's playing made Gary glad of a change? Couldn't Gary have just said that he was happy for a fresh sound and left out any criticism of Hadrien?
Anyway, great discussion.
