Akira Tsuchiya is still in Gust but who knows if he's actually composing any more; he didn't write anything for
the latest game he produced. Seems like Gust is content to rely on composers from other divisions in Koei Tecmo and outsiders to supplant their music team instead of hiring new people.
Maybe if a third Surge Concerto game ever comes out (
apparently it's confirmed it was started on), we'll see more Tsuchiya tunes.
