Pridelands is a band from Australia who just released a remarkable EP called "Natives." They have a sound similar to Architects (UK) and Periphery. If you're into bands like that, check em out!
Atrocities is a Christian Hardcore band from North Dakota, who just released a stellar Demo earlier this year. If you're into bands like Stray From The Path and Sick of it All, check em!
Number Them is a killin' post-hardcore band from Glasgow. Their newest EP "Cursed" blows my mind, and the album artwork is amazing! If you dig bands like Hundredth or Misery Signals, give em a listen!
