The pre-inaugural concert brings together pop culture, the dreams of Lincoln and King and the symbolism of Obama's election. It was a day that combined high-minded political rhetoric with the very best of pop culture. Tens of thousands of citizens, a throng more than a mile long on the National Mall, braved frigid weather and long security lines to attend a historic concert celebrating the country's first black president -- held at the feet of the monument honoring the country's great emancipator, Abraham Lincoln.
