Honestly, there's not much I can tell you about Erie, PA other than it was a railroad hub in the early days and then evolved into a steel-mill town.
Also, it's not too far from Buffalo, Pittsburgh, Cleveland or NYC.
This brings us to Abngeation - Erie's hardline sXe crew whose sounds was an amalgamation of all those flavors of the bands from the aforementioned towns.
While they may get lumped in w/ the militant hardline thing, their sound evolved in to one that included many elements of thrash/speed metal, as well as eventually becoming sludgy, dark & heavy.
These guys were unique in delivery, but sadly, they packed it in after five years while the rest of the world is stuck with ear-turds like Earth Crisis & Hatebreed...
