Bryan, as for emotion expressed and received; i've been playing with and listening to musicians a lot, mainly in the folk domain. Now and then you'll meet one of those magical entertaining performers who can really connect with your soul when they do their thing. It can be that they are real virtuosos, but also quite simple down to earth players, or even a story teller like a farmer i met in a rural Irish village pub years ago. But on all counts they draw you in to their magic like honey draws a bear, even when you know you'll get stinged sometimes. A mechanism Mao and Hitler too used for their nasty goals?
Even after their passing their soul's imprint on us all seems to linger on like the stickiest glue residue ever. Recordings, reputation, magic? Had an old aunt who told me she saw auras; from a great stage performer she mentioned she could see them mingle with those of an audience, uniting in colors. PS call me crazy if you like, but you'll not be the first, hehe. - nout
