Following recommendations in this thread
, I came across videos by a guy named Adam Fulara
Ho. Lee. Smoke.
Much like Michael Hedges, this guy is doing things that you just can't do
on a guitar. Don't get distracted by the faces he makes while playing, but do check these out:
"Prelude & Fugue in C-sharp Major BWV 848 no 3"
"Goldberg Variation No. 1"
"Just the Two of Us"
And, speaking of Michael Hedges (rest in peace):
"Because It's There" (on the harp guitar)
"Cello Suite #1
in G Major" (also on the harp guitar)
"Breakfast in the Field"
