Have any of you ever stood quite near Koko Bermejo (Affinity drummer) in any of their gigs?
Man, that guy grunts a lot! And he grunts out loud, especially if you can hear him amidst all that fancy drumwork he does.
And so does Johnny A ..
I haven't really heard them talk about it, but I guess it's got something to do with meditation, breathing and energy release, or something to that effect.
On another note, some guitarists have developed this habit of singing along with their solos. Not the loud George-Benson-type of singing, but a more subtle, yet still audible, scat-type vocalization that apparently helps them with their phrasing.
You can hear this a lot in Kurt Rosenwinkel's albums, particularly the 'East Coast Love Affair' trio thing. If you listen closely, you can hear him distinctively humming along in the background while he's soloing ... 
just as your breathing technique when you play a solo, kala mo i don't take notice, eh?
basta, with jazz, tone is in the bigote
but as for indiosyncrasies, i've found that folks that love jazz (and the bestest musicians i've met, including deacon here)-
- are in "like" with gear, but are in love with the music
- have the wittiest and quirkiest sense of humor! playing wise and conversation wise. Like deacon breaking into the riff of europe's "the final countdown", in the middle of "sunny", or dolph asking me to harmonize with him the harmony lead of francis m's "kaleidescope world" in the middle of a jazz standard. too much fun, i heard the siren's of the jazz police outside...
- have the deepest and most profound insights in music and life itself
- laugh at the gayness of benson (hahahahahah!!!) i love you george, and i don't mean "boy"
- i still consider myself to be sitting in the jazz stroller wearing jazz nappies and sucking on a jazz pacifier. but when i feel the groove and solo, i salivate to the point that there have been quite a few times that i have been caught, erm... dribbling across the court to the point of "travelling", hahahahaha!
off the top of my head...
