Crystalline is Hark's debut album. An album which has gotten hyped and praise from UK's Metal Hammer site. They're calling it a "sludgy, doomy riff-fest of a debut".
Even Metal Sucks has a lot of good things to say about the debut, ""Seriously, this record rules, but maybe down a couple of energy drinks before braving the terrain, and don’t expect it to sound like ANYTHING you’ve ever heard before."
