Did you hear a bone-chilling collective shriek coming from the Bryant Park this morning? It was just Miley Cyrus and her legion of tweeny-bopper fans piled into Bryant Park for an early morning concert courtesy of Good Morning America. To put some perspective on it, this was pretty much equivalent to the Bon Jovi concert in Central Park but for the underage set.

The 15-year-old wunderkind managed to put some age-appropriate clothes on for the early morning appearance, and performed a few tunes from her new album "Breakout," which will be released on the 22nd, but no "Hannah Montana" tunes (she left her Disney Channel persona and wig at home). Relive the magic at YouTube and GMA's website. Next Friday expect a slightly more mature crowd gathering for Feist, who is also playing the show's summer concert series.
