29. System of a Down
One of the few truly original and interesting metal band that appeared during late 90's/early 2000. I, like many others, got truly hooked on by Mezmerize and their success blew up so much it was kinda redicilous.
The thing that usually gets very mixed opinions is guitarist Daron Malakian's vocals. Others (which are pretty much the majority) don't like his singing, but I'm one of those who thinks it kicks ass. Either way, it fits nicely together with SerjTankian's unique voice.
Too bad that during System of a Down's hiatus Malakian hasn't done as much as Tankian has, solo-wise or with other projects. Because I think Malakian is by far the better/more interesting songwriter out of those two.
