The following message was posted yesterday at the Tennen-sozai feed on Bandcamp:

Hi, all. The publisher of the eXceed albums, Nyu Media, is closing up shop and these albums will be removed from Bandcamp on July 1st. If you haven't downloaded (or bought it!) it yet please do so ASAP.

Thanks very much for your support and wishing everyone all the best!!

I guess it's Nyu-Media who put up this page for them and so with Nyu-Media going out of business the Bandcamp page is going down as well. A reply in the comments of this post suggests the page might stay up a little while longer but I don't know how long.

FYI it currently has just three soundtracks:
* the soundtrack for eXceed 2nd - Vampire REX (i.e. the remake of the second game, which is also the version here on Steam)
* the soundtrack for eXceed 3rd - Jade Penetrate (i.e. the original version of the third game)
* the soundtrack for eXceed 3rd - Jade Penetrate Black Package (i.e. the remake of the third game, which is also the version here on Steam)

Here's their discography page: https://tennen-sozai.bandcamp.com/music

If you've already bought The eXceed Collection: Aural Brutality Edition, or if you've bought the Let's Build a Doujin Bundle 2 on Groupees[groupees.com] sometime back in 2013, you should have access to the soundtracks for the remakes of the 2nd and 3rd games (along with that of the 1st game), but not the soundtrack of the original 3rd game.

This is currently the only way I know of to get the soundtrack for the original 3rd game. (Which IMO is slightly better than the remake; the tunes are basically the same but are mixed slightly differently.)

(There's a (conspicuously different) soundtrack for the original 2nd game but I don't know where to get it.)
