in reply to 'bedokkids':
Classical doesn't emphasise technique over feel.
The only difference is that classical music requires the performer to be very good indeed, since the music is/can be very challenging to play.
But the point of it is not technique per se.
The technique is a tool to enable expression.
If you didn't learn how to speak, it wouldn't matter what emotions you had in your heart. Every time you opened your mouth, people would just hear a noise.
So it is with music. Technique is a path, and not the destination. The destination is the music. And in classical music, if the technique is lacking, then all one will be aware of is the technical aspect, and not the music. Pop is technically easier, and may 'appear' to be more emotive, but remember that you have a vocalist giving you a story - they are guiding your emotions. With purely instrumental/classical music, the music alone has to convey the emotions. So the player needs to be very good indeed. But this doesn't make the music less about feel and more about technique.
RE your question about classical music - for guitar-specific, check out Agustin Barrios Mangore, Castelnuvo-Tedesco, Henze, Mertz etc etc
A great piece is 'Koyunbaba' by Carlo Domeniconi (
YouTube - William Kanengiser: Presto from Koyunbaba (Carlo Domeniconi) - that is the 3rd movement). And in a nice tuning (open C#m)
The best recording of it is on a CD called 'The guitarist' by John Williams - it'll blow your mind
