Northless' Clandestine Abuse is basically a sludge album. But it is also much more than that: You can hear post-rock influences and math- and hardcore riffs pop up on many tracks. Parts of it have been described as "Krallice as played by cavemen", other parts as "Mastodon on barbiturates". Here are two reviews from Don't Count On It Reviews and Invisible Oranges. Northless also have their own Bandcamp where you can stream or download some of their older stuff.
