I agree totally. Most of the good country players, and I mean the really good ones, not the hacks who play in local bars, can play jazz at a very very high level. But most jazz musicians cannot play country worth a hoot. When it comes to versatility, the country musician is probably it. Country can be so many different things. A couple of years ago it was pop. Now it's more like southern rock. Then there's western swing. I know fully well that this was not a thread about defending country music, but I just had to get that in.
At the Namm show last year I was playing with a guy who used to play for Brooks and Dunn. We played a few country tunes and then he asked me if I knew any jazz. Later that afternoon I was playing guitar with John Pissano and we were playing jazz, and I launched into a country thing and he was just totally incapable. Wouldn't try taking a solo for love or money. Superb jazz player though. I was having a blast, because I don't get to play nearly enough jazz, especially with first class musicians.
As far as jamming with fellow synthzone members, has any of you tried ninjam? I haven't tried it, but I have heard some virtual jams that were recorded by some people who use it. Pretty cool.
