Spontaneous in example sentence
There had never been a female singer quite like her ever before, and there never would be again (sorry, Celine - only in your dreams!), but never again would Streisand sing with the vibrancy, energy, and, above all, the ENTHUSIASM and VULNERABILITY with which she performs here - by the time she gets to that Central Park concert only 2 or 3 years later, she'd been filming FUNNY GIRL in Hollywood and her performing style has become less spontaneous and more reserved, more rehearsed (and, let's face it: more angry) - there's a wall between her and the audience.
