Re: Dream Theater
Well from what I understand he asked if the band could take it's first real hiatus, which I could understand since he's been recording with half a dozen other groups over the last decade, but they decided against it since they wanted to get started on the next album next year rather than take a break.
I don't blame Mike or the other members of Dream Theater for him leaving but I really don't know how they're going to be able to recover from his departure. Aside from being one of the hands down most talented and irreplaceable drummers on the planet he also handled backing vocals, wrote a substantial chunk of the lyrics (especially after Kevin Moon left 10 years ago), produced their albums alongside John Petrucci, and handled a heavy share of the behind the scenes work. I mean, he really is probably was the hardest working member of the band.
