I bet Mike and Derek aren't too happy with this interview
Why wouldn't they be? If asked the same question, I'm quite confident that they would both give similar answers.
Mike and Derek might give similar answers, but they would wrestle with themselves (and lose) trying to come up with an answer that did not acknowledge or even mention Dream Theater, or if they did, that somehow Sons of Apollo is fresher, better, newer, something. Despite the fact that Mike is still and probably will forever be known primarily as the founding drummer of DT and that Derek was in DT for a while, thus the connection, they've tried like hell to emphasize that this is a different band, and seem to want to distance themselves from DT.
Then comes Ron telling it like it is. Sons wouldn't exist if DT had never existed and/or had the DT connection. That connection gave them some cred, and at the very least gave a lot of people a reason to check them out.
