@hulldanfan...had forgotten that George Benson could do a tasty take on "Take Five". GB has some pretty good instrumentals that are worthy of this list (beyond that one), IMO. George could definitely play on the edge of "too many notes, too fast". That's almost a requirement for some Jazz, though.
The too much, too fast "criticism" is occasionally levelled at Joe B and Walter Trout (among others). Never been a problem, in my book. Though I appreciate a slow chugger of a tune, just as much.
Back on topic, there's loads of Leo Kottke's fretwork that would make my list of fave instrumentals. "Bean Time" leaps to mind. Bet Joe could tear that one up, too.
And as acoustic guitarists go, Michael Hedges was no slouch, either. Not that he wanted to be known as an instrumentalist. His "Jitterboogie" is another instrumental on my favorites list. (Another artist that was taken from us way too soon.)
Play like you've worked at it, and don't worry about sounding like your influences. You can't cheat on them, or your practice, anyway. If you've worked hard at your skill, your audience will know it.
