Two more things occur to me:
- It's interesting that Roddy and Wildoer flat out said they couldn't quite keep up with the material. While I'm not sure how good they are in comparison to the other drummers, these guys are very good. It says a lot about how technically advanced DT really is.
- Also interesting about them is that, in a sense, they were just looking for a gig. I 100% understand this, but for DT it's not the best attitude. When you compare that to Lang (seemed to genuinely want to find a home in a band, actually very surprising), Minnemann (genuinely excited about the idea of the DT lifestyle), and Mangini (willing to quit being a professor at Berkelee), it's easy to tell why just from their attitude they didn't make it. I don't think this is a bad thing, different people belong in different situations and they did their jobs like professionals for the auditions. But it shows why personality is just as important as ability.
