I’ve found unconfirmed histories of specific companies/labels in google groups and a blog comment.
They both seemed to produce useful associations between people, companies, labels, releases and dates.
Though as already stated, the info is unconfirmed.
I’ve made one annotation that is probably too long. And possibly misleading. However it is the best info we have around this label (and other labels that are mentioned in the history too I suspect).
What are the views of others?
