Jazz gives me that intellectual lift. It's complicated and it allows me to go way out (which for me harmonically is not THAT far out). I'm fairly conservative. I always feel like I'm observing a little when I play jazz. Rock too for that matter.
The classical that I'm playing, and I'm really only a dabbler in classical guitar - perfectly fine for the occasion, but not the "concert" setting, has emotional resonance for me, but I still have so much to learn...
The music I feel like I'm playing from the inside out is the Americana/bluegrass and the acoustic music.
I feel such a strong emotional connection with the style. I've been playing since I was 5 years old and started on an acoustic guitar. I've had the feeling of having a acoustic guitar vibrating against me for more than 40 years - the ultimate security blanket. Playing those straight chords and deceptively simple melodies always brings me back to a place of lightness.
I've also found that the audience connects much more directly with the traditional music - which as as performer gives me some of the "sugar" that's so important. Don't let anyone who performs for other tell you it's not important!
