This is something I've been wondering about for a while, and the mixing/production topic brought it back to mind...
I know that Kevin Metcalfe was the mastering engineer for a lot of Blue Room Released albums. But I can't find mastering credits for several of their early releases (Etnica, TIP, TE, Outside The Reactor.) If you look at their Discogs entries, they just say "pressed by Disctronics S." While Dragon Tales lists the recording studio, but nothing else. Were these albums mastered by the artists/VA compiler, or was there an uncredited engineer?
