Sacred Reich formed in the mid-80's and was a big part of the American Thrash Metal scene along with giants like Metallica and Megadeth.Sacred Reich never achieved the mainstream success some of their peers did, but they had a strong following in the scene.  Bassist/Vocalist Phil Rand's politically charged lyrics and their aggressive sound found them often critically acclaimed even if they weren't a headlining band.

One could argue their sound was the beginning of the more aggressive groove-laden Metal sound we heard in the 90's.  Before Pantera was pounding away bands like Sacred Reich were paving the road for them to travel down.

From their 1990 release here's the title track to "The American Way"
