Most of the time, even in jazz that sounds techincal, the music is about everything but techincal perfection, IMO.
Yngwie malmsteen is more about technical perfection than, say, John Coltrane. I WOULD throw Allan Holdsworth under the technical perfection light, but he, too, also has some very deep, thoughtful melodies and songs.
The Yellowjackets are more of the breed of modern pop/jazz. I would associate the term "Modern Jazz" with the likes of Brad Meldhau and Jason Moran. But jazz is changing every day. There are many who would call anything Post-Charlie Parker as modern jazz. The stuff that was modern yesterday (like Joshua Redman and Mulgrew Miller) isn't really what we're hearing today from Kurt Rosenwinkel.
It's very deep and complex -______-
For me, elevator music is more along the lines of Marcus miller and some of George bensons smooth jazz escapades. Also, a lot of the Pat Metheny Group (w/ lyle mays) sound elevator-y to me.
For modern jazz that isn't lifeless and mundane.... check out these guys:
Kurt Rosenwinkel - "Heartcore" , "The next Step"
Avishai Cohen - "Lyla"
The RH Factor - "Hardgroove" , "Distractions"
Gary Thomas - "Til We have Faces"
Really, everyone has their tastes. Malmsteen is an awesome player, but I just don't care much for his music, plus he sounds the same to me all the time. Kurt R and Adam Rogers to me are in the same boat, but for different reasons. I find their playing benign with lack of any dynamics, but I like a lot of their music
. At least when they're with the right people. I wish I was half the player and musician as any of these guys, however! I like Holdsworth, Vai, Govan, Reyes and Abasi (in T.R.A.M anyway), Robin Ford, Martino, Di Miola, and Summers, even though some of these guys may be more jazz rock, but whatever. Robin Ford (jazz blues?) in particular is great with wonderful dynamics and intonation, one of my all time favs (and played with the Yellowjackets for a stint).
With sax players lets not forget Brown and Mobley. I particularly like Mobley's melodic style. Not a sax player, but still very young, I like Christian Scott. I'm not sure the definition of "modern jazz" but I would put it more around the 70's. Or maybe with Scott. Yeah I know many consider be bop modern jazz. But that came out way before my time to be modern
And to dpattillo's point, I saw Elian Elias at Filoli and she was out of this world. I also recently watched Grace Kelly on a PBS concert and she blew me away. Yet, neither of them seem to have that energy on their albums. Not saying their albums are bad, just not as good as you would expect after seeing them live.
