I always thought that Austin's vocal styles would be as close to Mitch's as one can get. Maybe not his lows, but his highs yes. Mitch was just the best metal vocalist around. He was in his prime and it's awful he went the way he did.
This and Phil Bozeman's performances are killer.
I've never been an SS fan, but this show was definitely a great idea and I would have liked to have been there.
