For independent labels:
Also, Black Mark (Edge of Sanity, Bathory, Lothlorien, Tad Morose, Morgana LaFey) and Spinefarm/Spikefarm (Finntroll, Children of Bodom, Darkwoods My Betrothed, Kalmah, Nightwish (Though Nuclear Blast carries foreign distribution nowadays)). Osmose in the old days but they've gone downhill (lost Marduk and Immortal, etc.)
Also, the big boys of metal, Nuclear Blast and Century Media, but I doubt they really count as independent anymore (Certainly I can't imagine anyone who sells branded Dimmu Borgir pyjamas to be indie).
Roadrunner does actually have a few decent bands on it, but they certainly aren't the ones they sell to the public (I'm thinking of Illdisposed, 3 Inches of Blood, etc.)
