I get why he is pissed. I'd be pissed. There's a lot more behind that frustration that you guys might not know. One thing is that Portnoy has an endorsement contract with Sabian and he should always be playing Sabian cymbals but for some reason these tech guys got him Zildjian cymbals for that tour so they forced him to infringe his contract throughout that whole tour. And this is just one of the dozens of things that went wrong.
Still he is a performer and his contract bullshit is not the crowd's business. He should STFU and play the gig with positive spirits no matter what.
A funny thing though... stuff like this used to be considered cool. Metal bands trashing the stage etc. was "rock'n'roll" ... but I guess Portnoy's girly attempt of being a rockstar doesn't belong in that category.
I love Portnoy but had to say this.
