It is sad, and I think it's something the Scott defenders here seem to be forgetting: From what we've heard so far, Scott's relationship with his bandmates had become solely a business arrangement. They didn't talk, they didn't travel together on tour, hell... I don't think they really liked each other. And how can you blame the other three after all the embarrassments Scott caused STP? It sounds like it had gotten to the point where when Scott had an obligation with the band, he showed up [late and drunk], did his part, collected his check, and went home. If you need to reach me, contact my manager and he'll get me the message. Who would want to be in a band with that guy? Whether because of ego or addiction (probably both), he had become an awful bandmate. Even at that level of success, I would think bandmates should still get along well enough that they can call each other on the damn phone.
Enter Chester -- a guy who is an established singer in his own right, with another wildly successful band, who happens to be a huge STP fan and has a history with the band. Not only that, but the guy shows up on time, is a joy to work with, and does a damn fine job of crafting quality vocals, while staying faithful to STP's legacy. It's a no-brainer.
Seriously, how can anyone defend Scott anymore? I love the guy, but he fucked up. Plain as day. The Deleos and Kretz are 100% in the right to have fired him and brought in Chester to continue as Stone Temple Pilots.
I don't think Scott is a bad person. He was my idol growing up, and I still admire him for everything he's achieved as an artist. But even our idols make mistakes, and let's face it: he has made A LOT. I wish only good things for Scott, and I will still be following him in his career, because I will always be a fan of his. But I also hope he finds some humility. I think his life and his music will be better for it.
