No, sorry. I didn't know. I thought that additions of artists and/or albums were always in charge of admins.
Time ago I downloaded GTR2 without knowing that it was a bootleg. I opened a thread like this and somebody informed me of that, so the site was safe from a mistake and the error team didn't have to delete it.
About this one, it's different in some ways from the original of 1972, should it be addef (if should) to Showmen or to Napoli Centrale? I can't answer this question alone, at least not before having listened to the first to see how much they differ.
A similar case that I'm sure you know: a disk whose title is "Marian Varga and Collegium Musicum" has to be put in which discography? Both exist on PA and it's something more than a collaboration but too few to introduce a new "entity" It's not the same as Jon and Vangelis for example. They are not Jon and not Vangelis. Marian Varga IS collegium Musicum, instead.
