While I do enjoy a handful of their releases (BLOODLUST, HEXX, HELLWITCH..) I honestly think they were one of the weaker 80's labels as far as quality control goes. They did however pioneer a few cutting edge cult-acts like BLASPHEMY, NUCLEAR DEATH and IMPETIGO, so I'm sure fans of the more extreme Metal won't agree with me.
Generally, the most active debate around the label seem to be weather they were an Evil Rip-Off Label or super-cool and generous with massive promo-packs to both zines and scenesters. Personally I'm quite impressed with the amount of work that must have gone into it, especially considering it was basically a one-man operation. For some really interesting reads on the history of the label, check out these two articles! They also ran a fanzine "The Wild Rag!" - check The Corroseum's Fanzine Library to see how many we've managed to preserve for your reading pleasure (at the moment of writing I only count one):

This page covers their discography up until their last 12" vinyl release, including the 8 releases on the European branc of the label (Dutch to be specific). The quickest way to tell them apart from the US versions is these have barcodes on the back - the US vinyls doesn't.

The label continued to release CDs, 7"s and demo tapes up until the late 90's, but they were all in the Death/Black/extreme Metal field = not for The Corroseum.
