I've watched the audition video a few times now and a few things really stand out.
What a fantastically nice bunch of guys DT are. I've met many very talented pro musicians from all styles of music and there are many, many real ego fuelled ***** out there.
But with DT the whole band just come across as genuinely great people.
Mike Mangini just lights up behind the kit. Just ignoring his amazingly massive musical talent for a moment (not very easy really :D ) as soon as he starts playing he seems to be ten times more alive. I know musicians usually feel more at home behind their instruments but he is something else!
He also seems fantastically humble, he really wanted the job as drummer in DT and seemed overawed to get it, not what you'd perhaps expect with his playing credentials.
So not only are DT amazing musicians they are nice people too.
What a band :D
