I don't see the resemblance, I think you assumed that is was similar to roots because they have non EU people performing ceremonies?
Btw they play this every show now as intro to their set.
Fairly accurate assessment aside from the non-EU thing or whatever, as I was just thinking it was a bunch of Greek dudes who were yelling in Latin about Satan or whatever it is they're pedaling. It was the 'tribal cadence' which they borrowed that I was more thinking of IIRC. The album itself is growing on me quite a bit.
