Some people when asked that question try to give an answer that will impress but I will not. I do not listen to anything profound, nor do I wish to hear anyone showing amazingly dextrous technical guitar ability for its own sake. I do not want anything that claims to solve all the world's problems. A pleasant sound is as much as I seek.

It is easy to criticise organ players as not really musicians because of what you can set up the instrument to do just by pressing one key but here is someone who genuinely plays properly, one note per key press etc.
I really like Claudia Herschfeld. She plays like an orchestra. Here she is (https://www.youtube.com/watch?v=GgACwGkWde0) playing the John Miles 'Music', here playing 'Eye Of The Tiger' (https://www.youtube.com/watch?v=j5K44Nf9d3o) and the 'Star Wars' theme (https://www.youtube.com/watch?v=o5djMNiopDM).

John Miles is a favourite of mine. He does a lot of big orchestral pop / rock concerts all over Europe as
the main piano player accompanying various artists. It is clear here (https://www.youtube.com/watch?v=YrOfa_gWg04) that he can sing, play guitar and piano
'live'. Being able to play 'live' is important to me.
