Agree with you 100% on both Lars and Fenriz. Fenriz showed off his chops on Soulside Journey, and after that has always been a solid backbeat for the riffs. He said it himself, Darkthrone is a riff band and his drums always compliment the riffs quite nicely. His work on the newer albums especially have been awesome and enjoyable.

Troll!! Hoglan has awesome speed, power, AND variation. I mean, if I had to say three qualities that were best about Hoglan, it'd be these three things. Maybe consistency/accuracy over speed, but still.

I have to agree with Lars Ulrich. Awful drummer and his success/fame is completely undeserved.

Some guy said Gene Hoglan
Hoglan is one of the best drummers, with much power, speed and variation. Even in his albums with Death and even Dethklok... a good drummer, excelent, if not, perfect.
Lars Ulrich to me it's not so bad. I like him in One (specially in this song) Trapped Under Ice and Fight Fire With Fire. Not the best drummer in the Thrash scene (Dave Lombardo perhaps ), but an average drummer. And yes, he's better than the drummer of Pelican.
That skill is very very simple and easy. Lacks of speed, and variation (again, specially this)

I don't understand all the love for Dave Lombardo. I've always thought he was a decent drummer but when I saw Slayer live he was sloppy as fuck. Really disappointing. Although to be fair, it was not Slayer's best night (Tom Araya couldn't sing, sound problems, etc).

I'd second that comment about Varg's sloppiness (especially on Det som engang var) but you do get used to it over time.

As well as Paul from Cannibal Corpse. While he might not be the worst (far from it IMO) he is very uninteresting... and too slow

I've never found anything praise worthy about Louie Clemente (Testament). When he comes on to drum on the Live in London DVD... uggh.
