You could always check the live footage on youtube? I've yet to attend an Evile concert in Canada, so I'm patiently waiting (DON'T COME DURING WINTER PLEASE!!!). But from what I've reviewed, he seems like he has more control over when to sing and when to use power in his vocals (using Infected Nation as an example, since before he was being too hooky on that song sometimes). Live, a good 60% of the time he's more powerful on stage than on the record. Shows during some peformances of FST, Cult, and in some cases Descent Into Madness.
