Actually, I have to confess: I don't know.
Around the time when TMI was released, someone from the band said in an interview that The Gallery had sold about 25 000 copies and ESA something like 6 000. At that time they didn't yet have the numbers for TMI, but they predicted that it would sell about as much as The Gallery.
Now, however, we must note that the above information is over four years old - thus I'd believe The Gallery has sold about 50 000 copies; whereas Projector and Haven (supported by a bigger label) have probably sold far more.
So, here are my "educated guesses" in this matter - they might be wrong by lightyears, but unless someone can tell us some actual numbers, this is the best I can come up with:
Skydancer (original) - 10 000
OCaEN (original) - less than 5 000
The Gallery - 50 000
ESA - 10 000
TMI - 50 000
Skydancer + OCaEN (re-releases) - 15 000 (?)
Projector - 80 000
Haven - 80 000
That would be a total of 300 000 albums sold, which is actually quite high for this kind of an unknown band. Perhaps the numbers of The Gallery and TMI should be dropped to 40 000 each and the numbers of Projector and Haven dropped to 60 000 each. That would sum up as a total of 240 000 albums sold, which sounds a bit more reasonable than the previous number.
Other ideas?
And sorry, Misanthrope, you left me no chance to ignore this challenge.
