They did a series of videos for the drummer auditions a couple years ago when Mike Mangini got the job after Portnoy left.
This is part 1. There are at least 3 (I didn't see part 4, but can't swear it doesn't exist).
Marco Zinnemann is a monster, and part of me was hoping he'd get the gig, but I didn't want him to have to give up on the Aristocrats (there's a band that's sick with talent - maybe I'll start that thread!). I talked to him at an Aristocrats show and told him that, ultimately, I was glad he didn't get DT and said I was torn watching the auditions. He said he was disappointed not to get it, but it was all gone the next time he played w/the Aristocrats. He did say it was actually probably better that he didn't get DT because he'd have had to give up some of his other stuff besides the Aristocrats because of the demands of the DT gig.
