Like I said before I have a very wide music spectrum. I like Folk, Alternative, Rock, Metal, Indie,Pop, Swing, Electro Swing, classical, instrumental, punk, House, rap, dance, any variations of these, pretty much anything but Country. My favorite genres are Rock, Punk, and Alternative. My favorite bands being Switchfoot, Relient K, Thousand Foot Krutch, and House of Heroes.
No, that song would be classified as Instrumental Progressive Metal. The differences between Instrumental and Classical are that Classical is well a Classic. Like books for instance you have Classics and I'm assuming you know what makes them a classic? Same goes for the music genre.
