Sigh is still kicking and only get better. A few people will tell you they peaked with Imaginary Sonicscape, but I like the newest ones just fine. Gallows Gallery has Maiden-esque riffs for days and days.
Thar be a lot of garbage being dropped in this thread, haha.
Get the new Slough Feg, Warning, Sigh, Darkthrone, and Pale Divine. Would I lead you down the wrong path? Well, yeah, but that shit is solid.
