The Japanese two disc soundtrack for Castlevania: Order of Ecclesia features “more of the same” from the Castlevania series. And that’s a good thing.
Now when I say “more of the same,” I don’t mean you’re going to hear 8 arrangements of “Vampire Killer.” They actually didn’t borrow many tracks from previous Castlevania titles. But stylistically, yes, it sounds just like a Castlevania soundtrack.
My favorite thing, consistently, about this soundtrack is the bass. The synth bass lines are awesome. Whether acoustic, electric, funk/slap, or other, the lower tones scattered throughout these songs sound awesome. Somehow, they survive the DS compression. They sound different, sure, but the DS sound source doesn’t make the bass sound bad. It sounds old-school and cool: totally appropriate for a Castlevania game.
Now, I would recommend this soundtrack to you. There’s just one problem: you can’t get it. Even though it has the standard Konami Style LC- catalog number (which makes you think Konami would at least be selling it via their own online store), this soundtrack was only made available to those who imported the game, and even then, in limited quantities. This soundtrack is part of the ridiculous 18 CD Castlevania box set released in 2010, though… so that might be a (very expensive) way to get it – though I’m told even that doesn’t contain the full two discs of music found here. Also, as a last resort, you can enjoy the grossly compacted six-track American release.
