“……….no genre boundaries”.
No matter the genre, sometimes a performance is so locked in and with such strong collective sense of purpose that it brings a different meaning to “spiritual”:
Perfect description of the vast majority of the performances of guitarist, Allan Holdsworth.

As a good friend and a top LA studio musicians said about Holdsworth:
"For me, Allan Holdsworth was the most innovative improviser of all time on ANY instrument. The great jazz soloists (McCoy, Brecker, Freddie Hubbard, Trane, etc.), all had predecessors on their respective instruments that they copped licks from and modified with their own voice. There clearly was no guitar lineage leading up to Allan's approach. This freak landed ship with a completely new vocabulary not based on anything that was already established. No blues, pentatonics, bop, post-bop...NOTHING"
