Re: Dream Theater's new drummer
I believe Derek touched on it earlier in the thread: They pretty much knew who they wanted anyway. Mangini has been an obvious choice from the beginning, and a good one too. The auditions seemed to be mostly a publicity thing.
The seven guys they chose are definitely amazing drummers. However, there are many others who would be a better fit musically but who wouldn't have brought as much "fame" to the table when it came to making the audition process public as they have done now.
Disclaimer: This is obviously only my take on it, and it's based on the extremely small amount of information that has been made available. I'm probably wrong, but it can be fun to speculate sometimes.
