As they said many times in The Godfather, it's only business; it's not personal. But that sucks. Making music with other people is as personal as it gets. It's a bond. Dream Theater themselves used to speak of it being like a kind of marriage with five people all trying to compromise and cooperate. But Derek Sherinian was not the original keyboard player, therefore the others could decide to can him and get someone else. JLB was not the original singer, therefore he would've been gone if MP had convinced JP to pull the trigger. And now MM is out because JP wanted MP back.
Notwithstanding that some of that is still speculation, but why can't it be both business and personal? And even if we think the "business" is not that big a deal with a band like Dream Theater, as I noted in a previous post, sometimes the personal is multidimensional. We're all looking at this from Mangini's perspective - how could John DO this to such a nice guy!! - but we seem to be forgetting that bringing back the guy that you played school janitor closets with, that you figured out how to use a Tascam 4-track with, that you toured the world playing shitty clubs with, that maybe you banged groupies with (or whatever they did back then at Berkelee), you broke bread with at every holiday, that your wife and his wife are best friends, that your kids are also best buds... Bringing Portnoy back is, on some levels the MOST personal of all moves.
I don't know about some of you but I have friends, and I have "FRIENDS". I'm close with some people here, and we sometimes text about personal, meaningful things, and many of them have been solid as rocks when I went through some bad shit (losing my parents). And it means a lot. More than I can ever say or repay. But I can recall, about a year ago, I was at dinner with some friends from college and one of them pulled me aside and whispered in my ear "Dog, I've been there, and we're here for you hell or high water", and knowing that we've been through everything - births, deaths, divorces, marriages, more divorces, rehabs, moves, firings, hirings, etc. - for the better part of forty years, is not the same thing. It's just not. I don't think we can, from the outside, ever understand the real depth and dynamic between two people so closely intertwined like John Petrucci and Mike Portnoy. From the standpoint of 40 years of FAMILIAL bonds, 12 years is like a blink of an eye. I don't mean to minimize the shorter relationships, not at all, but just saying, to compare them is fraught with peril.
