Motoi Sakuraba
Motoi Sakuraba is a great composer. Not really sure about this though, it sounds similar to Motoi's works to a degree, but newer games are differently styled now ever since Motoi met up with Noriyuki Iwadare it seems.
Anyway, it's a good song. Also, Motoi didn't just do the tales games, Motoi also did the Star Ocean series and Golden Sun Series (as well as Valkyrie Profile series.) Whilist, Noriyuki Iwadare loves to remix Motoi's work a lot in new games like Radiata Stories.
Noriyuki Iwadare composes the music for the Grandia Series.
