I remember ordering Revenge's demo "Attack, blood, revenge" a few years back and thinking how their style of blasting war metal was unlistenable, but passable for a band that was just starting out. This is my next encounter with this band, and things haven't changed much, which isn't really surprising. I've learned that there has to be a level of memorability in a record that will make me want to play it over and over again. But like Sadistik Execution, who actually bore me to death, Revenge relies on speed to make its point across. The execution is tight, but really how long can one stand hearing an overwhelming amount of non-stop blasts and monotonous riffs? Luckily, this is only 28 minutes long. But still, after listening to such a record, you feel like you have just been through a hostile, adverse environment and usually that would be a complement to a metal band, but not in this case.
