Gargoyle, the Japanese one, just one of dozens of smorgasbord J-metal bands throwing random ingredients onto a bland metal plate. Good lead guitarist doesn't save them, every album I've heard has a couple good songs in the speed/power/thrash vicinity, and greater amounts of lolrandom shit.
Hobbs' Angel of Death, see Exumer.
Immortal, one good album (their first one), otherwise very bland from what I've heard.
Incubus, because Burns-era Sepultura wasn't dry and chuggy enough, we need to praise an even less interesting version of that.
Jag Panzer post-80s.
Kreator, for the most part. Yes, Pleasure to Kill is masterful. Other than that, hard to give a shit. They weren't pioneers beyond that one album, they were late on the scene compared to Destruction and Sodom, let alone the Bay Area. Endless Pain is a trivial album, Terrible Certainty and Extreme Aggression show improved technical abilities at the expense of energy, Coma of Souls is more watered-down than what even Testament was doing at the time. Renewal and Cause for Conflict are a little underrated by fans, at the very least they were mild experiments and showed ambition, but then you have 20+ years of sucking it to follow. Fuck Kreator.
Lulz Rockit.
