I've seen Kelly in concert three times. One of those times, it was all hyper with elaborate sets. Honestly, she spent more energy on jumping around and being rowdy than she did on hitting the notes. It was more like she screamed the songs. Don't get me wrong - I loved the energy. It was a fun concert.
But the second time I saw her, my husband was astounded. He said, "Dang, that girl learned how to SING". No - it was just that she was calmer, more laid back and focused on the singing. THAT concert was the best Kelly concert I've ever been to - no hype, no fancy stuff - just her amazing voice.
Sometimes simpler is better.
