Winery Dogs are alright, but far from amazing. Heavy metal is Portnoy's calling, that's the type of music he should be doing. He needs to stop these projects, and joining established bands etc. What is love to see him do is form his own new metal band, where he's main man, the Steve Harris of the group. I'm glad he has nothing more to do with Adrenaline Mob, they weren't good enough.
I could see him creating a new band that creates progressive metal. Progressive more in the vein of Tool rather than Dream Theater for example. That's what I want to see. My guess is that if MP could have had it totally his way there would have been much less 'wankery' in DT. I say this because most of the wankery' in DT is about the keyboards and guitar. I can see MP in a band that's more progressive in the way Tool is, where there's more of an overall focus on percussion.
