One of those groups that are Circle 1 for me, but not that genre in my head. They have a unique sound it being dense, driving, distorted with its own kind of groove. The guitarist is known for using chords that are not standard in rock.
And they have another quality: there are almost no songs I don't like from them. Sometimes I listen to them incessantly for days. And then stop for a while. I'm still putting them in Circle 1. I like them that much when I'm in the mood for them.
