Stuntgibbon,

I was intrigued by your description of Mastery, "Instrumental thrash riffing marathons!" this made me think of Orion, Call of Ktulu, and To Live is To Die and I started drooling...

I checked out some of their song clips on amazon, and I really liked what I heard. They did sound pretty repetitive, but I don't mind that at all if it's really good. - Wow, I'm listening to a clip of "Power Race" right now, and it's goooood -
So does it get old or is it so good that you don't mind the repetitiveness?
