American Idol finalist Chris Daughtry will perform a free concert in downtown Greensboro on March 23.

Greensboro Coliseum officials organized the show as a prelude to the NCAA women's basketball tournament games on March 24 and 26; they hope the concert helps the city's bid to host the 2012 women's Final Four.

Between 6,000 and 7,000 people are expected to attend the concert.

Daughtry, meanwhile, just achieved the top ranking on the Billboard album sales chart. It's an impressive feat for a CD that's been out for over two months already.
