The Season 10 finalists were invited to participate in a musical showcase with Grammy-winning artist Irvin Mayfield and the New Orleans Jazz Orchestra Oct. 8. In addition to the 18-person big band orchestra and Mayfield, the night will feature jazz vocalist Dee Dee Bridgewater, the acclaimed Sphinx Virtuosi and other special guests.

The orchestra is celebrating its 10th year in music, and Reinhart told THR that she is honored by the invitation, which came after an impromptu performance with the jazz legend in New Orleans.

"It is remarkable how one experience can lead you to another," said Reinhart, who recently made history as the first American Idol finalist to perform at Lollapalooza. "If you're ever questioning whether or not you should do something spontaneous, I highly suggest you go for it. One late night in a New Orleans jazz club has now led me to the ever so honorable Carnegie Hall. Irvin Mayfield is an amazing musician and great hearted person. I'm so privileged he made me a part of his big night."
