I really wanted to go the Mesa, AZ show the other night but I don't have my vehicle at the moment and couldn't find a ride.
You should check out some of Vader's studio recordings. They incorporate a lot of old school thrash feel into much of their material and the vocals are not your typical guttural death vocals. Very heavy, but more shouting than "growling" and not indecipherable like a lot of death vocals. Good stuff.
