As per usual, whenever the subject of Fusion (or just about any type of Jazz, come to think of it) comes up, everybody starts to take a walk down memory lane. I'm 55 yrs old, was fortunate enough to have seen original Mahavishnu and Return To Forever in small clubs in NY before they went 'stadium', and I STILL enjoy Fusion to this day. But as much as I dig the old stuff, there's NEW material that's really and truly, KILLA! I've done this before and it's usually ignored BUT, y'all can't say you ain't been told;) Here ya go, I'll give you specific recordings or just the artist/band.
Adam Holzman (Mile's last keyboard man) - Jazz Rocket Science
Alan Pasqua - The Antisocial Club
Cab 2
Cab 4
Dave Weckl Band
Dennis Chamber - Planet Earth
Greg Howe - Extraction
Jing Chi
Karizma - Document
Simon Phillips - Out Of The Blue
SMV - Thunder
Truthfully there's SO much more but anyone that's serious about Fusion will enjoy the HELL outta this short list.
