wtf krow? you're on crack, symbols of failure (third release) is by far their best and one of the all time greatest technical death metal albums, i can listen to that all day fucking long, it is so fast and technical it's fucking amazing and the vocals are insane. PICK THAT UP
and they have progressed, the first two are sort of like average death metal stuff but with symbols and observant it's much faster and technical, all around a greater sound.
