Perhaps the poor dude is suffering from burn out or has overdone it and is crashing? Maybe we should all be a bit more charitable? (and I sounding like a hippy here?)
I agree with that one Elliot ; as although I do not condone a lot of what he says - and how he acts of late, it does have all the hallmarks of the inevitable crash - after trying to maintain a larger than life persona as his 'schtik' .
Of course he could also have just become a spoilt brat ; but as has been demonstrated, the 'real' Zakk used to be ( and therefore at some level might still be ) a much straighter and sincere man.
It's like watching ( or being ) a manic person crashing through that hypothetical 'zero line' to an equal and opposite level of despair. Meanwhile , I just hope his wife and kids are getting good treatment.
As for his Black Label era albums ( specially 'Sonic Brew' and 'Mafia' ) - they are still my favourite choice to have a good weightlifting / kettlebell workout to. The 'sameyness' that folk sometimes complain about, works well for me there - in that it hits a groove and just keeps going , in an apty focused, chuggy and squealy way. Straight ahead Rock to accompany straight ahead hard work.
I hope he finds resolve and a balance before it's too late. :)
