Yeah, Orpheus, I was trying to be as straightforward as I could when describing the technical differences between the two genres. That, though, doesn't mean I prefer one genre over the other. Particularly, when it comes to the guitar, blues has it all over jazz in my book. To my ears, most jazz guitar playing comes off as fussy, smug and under powered. More interested in technique than passion or emotional expression. As a matter of fact, the only jazz guitar player I ever truly loved or aspired to play like was Django (and I do relentlessly play Django-style guitar and Stephane Grappelli-style fiddle). Good blues & rock guitar playing, by contrast, truly plumbs the emotional depths. Happy, sad, angry, ironic, jubilant, tender, strutting...guitarists put it all on the table.
