I toss this term around at times if the artist/music/venue/audience is a bit off, they are still there: no stopping and occasionally rescue what was seemingly a pathetic and anemic performance. I am no a performer, although I must admit I do fairly well with most Cream/Blind Faith tunes: but that just reveals my old age.
Is it just being comfortable on-stage while a whirl wind flows around it? Which I can imagine happening in any large venue with set production values.
I would love to hear your thoughts - first person, second-hand, let me hear it. The music business and performing in front of strangers is as daunting as it was 35 years ago. Except you guys and gals have more cool toys to play with. :).
