Pink is a great vocalist. Most critics understand and her peer musicians get this. Singing live, sans enhancement, is challenging. Live vocal performance within key , and perfect pitch is rare. Imagine adding the Olympic challenge of high wire acrobatics to the mix? Hush now. I prefer the vocal acrobatic octave range A capella Pink. What about you?
