I'm still relearning keys and jazz isn't quite my thing, but I found another jazz player on board. Couldn't tell you whether he plays smooth jazz or not, though.
I do some jazz playing (or, more often lately, inject jazz influences into the playing I do at church), but I'm not really a smooth jazz fan. Some of the music by The Rippingtons and Spyro Gyra is about as close as I get to smooth.
