What makes a performance "enjoyable"? Unforgettable? Moving?

Is listening to a musical performance more entertaining when it is more expressive? Can a naive audience tell when performers are on the same page, in sync, or on the same wavelength, and does that actually result in a better experience?

Comparisons will be made between high expressivity and low expressivity recordings from previous studies, and also between congruent and incongruent duets.

What factors, if any, including the expressivity, emotional intent, successful interpretation, and EEG-based neural synchrony directly affect a listener's subjective enjoyment? Moreover, does enjoyment, immersion, and feeling of connection correlate with higher neural synchrony to the performers?

Can we bring live performance to a new level by using real-time hyperscanning and neurofeedback to increase synchrony?
