all of them are good, Of Malice features their old singer, Jesse, while Mirrors is the first album that has Karl on vocals. You could just start in order of how they were released (Of Malice, Mirrors, Controller), you can't go wrong either way.
great friggin review dude.
Im a huge MS fan and love all of their albums. i have yet to get my hands on their s/t ep since it is out of print, but im keepin an eye out.
