I changed my opinion alittle bit about it cause Practice f. example sounds as a whole very the same and Metallica influenced though it has excellent leads!
The Production for Low and the Legacy sucks, they could have done it better..
The Ritual is okay but not really Testament, the new one too..but my alltime faves are:
1) The New Order
2) Souls of Black
3) The Gathering
4) First Strike still Deadly (though it's not counting as an "album")
