If anyone is interested in exploring this style of music in more depth, I recommend looking into "Third Stream" music. It's meant to be a sort of fluid combination of both jazz and classical styles, and is often pretty interesting. There's a whole lot of things that third stream music /isn't/ (and famously, a list that attempts to define the genre in terms of what it's /not/ supposed to be), and as such, many people who try to write third streammusic end up creating music that's a lot less subtle.
It's not really my cup of tea (more of a jazz guy), probably because there isn't a huge repertoire of third stream music out there, but it's definitely worth checking out if you think you might be interested.
