I don't normally associate Castlevania with horror, but there is an undeniable connection given its subject matter; mainly, vampires are a horror concept, therefore vampire hunting is a horror related concept, if otherwise lacking horror themes. Hitherto I'd never listened to the soundtrack for Symphony of the Night, simply because the most lauded tracks of the franchise come from other games (e.g. "Bloody Tears," "Vampire Killer," "Divine Bloodlines," etc.). I am aware that this game is one half the foundation of the metroidvania genre, and that being a favorite of mine, you'd think I'd have taken time to look into it sooner.
Regardless, I've taken the time now, and have been suitably impressed; far from the outdated soundfont style I expected, the arrangements sound almost modern, with full orchestral and electronic elements. There is a slight resonance issue that gives away its age, but I find this highlights the atmosphere as an unexpected boon. I was previously familiar with Michiru Yamane from Bloodlines, which for some time has been my favorite soundtrack in the series, but as that game was for very different hardware I didn't base my expectations off of it. She was also involved with Bloodstained, but I hadn't previously paid as much attention to which tracks she worked on; I'll be sure to check back on that now.
