This will probably sound strange but there's an old PC game called Total Annihilation that had pretty good orchestra music. In fact I would venture to say of all the games I've ever played the sound track to TA was probably the most brilliant especially if you're a fan of classical musical. A lot of times when I would read I just popped the game disk in a cd player and would chill out to the music while engaged in whatever book I was reading.
So what do you listen to when reading?
