Uwharria. From my home state and featuring members of Blownapart Bastards (as well as Rentamerica, Divide and Conquer, and even Oi Polloi) Uwharria played a chaotic brand of metallic hardcore that brings to mind late 80's crossover thrash - like later D.R.I. or Animosity-era C.O.C. Rick from Blownapart's vocals remind me a bit of Blaine from the Accused on these tracks which only adds to the crossover feel... All the lyrics concern wildlife and environmental issues (hence the "eco-thrash" tag) but with somewhat of a tongue-in-cheek attitude. Song titles range from bird species like "Ivory-billed Woodpecker" and "Appalachian Skullcap," to the less than majestic like "Dung Beetles" and "Tick Attack." Short-lived, Uwharria released a full length CD and a split CD with fellow N.C. punks Crimson Spectre. I remember there also being a live CD that the band self-released but I never got my hands on that. The link below has the full length as well as their half of the split CD, 24 tracks total.
