Hi,
My take on this is that too much of this is stuff that is more commercially appreciated than the rest of the stuff out there. There are many roles for the guitar that are not enjoyed by many folks, and in the end, we're comparing apples to oranges and I find this sad, since it hurts the ability of people getting a better idea of what the guitar can really do in various settings, many of which are not pop songs and just blues affiliated material.
I can't help feeling that this is just a commercial pitch for the same thing to convince you that there is nothing else out there in music. And that's a shame!
You'll never be able to create a Symphony for a guitar, or a true Concerto for a guitar and place it in a more interesting place than a rock/pop song.
Missed on the list for me:
Mike Oldfield
John Weinzierl (AD2)
Michael Karoli (late CAN guitarist)
Toni McPhee (Groundhogs)
David Clark Allen (Carmen)
Richard Thompson
Egberto Gismonti
Jorma Kaukonen (Jefferson Airplane and Hot Tuna)
...
that will do for starters within 5 minutes!
