"I've never read the cs Lewis book. Is it good?"
Only one of the best children's books ever written.
"How'd you get your guitar to sound so good?"
Just a pair of 1/2" condensers in an X-pattern about a foot away. Yes, most classical guitar is horribly recorded. They usually insist on distant mic'ing and then lose all the dynamics and overtones of the instrument.
I've had the piece around for a while now. It was written along with a couple of other specific pieces for a documentary on CS Lewis, but the filmmaker lost his funding. I don't normally do paint by numbers music, but it seemed to fit the subject.
